For example, a\nprocess will not be able to execute a setuid binary to change their uid\nor gid if this bit is set. The same is true for file capabilities.\n\nAdditionally, LSM_UNSAFE_NO_NEW_PRIVS is defined to ensure that\nLSMs respect the requested behavior.\n\nTo determine if the NO_NEW_PRIVS bit is set, a task may call\n prctl(PR_GET_NO_NEW_PRIVS, 0, 0, 0, 0);\nIt returns 1 if set and 0 if it is not set. If any of the arguments are\nnon-zero, it will return -1 and set errno to -EINVAL.\n(PR_SET_NO_NEW_PRIVS behaves similarly.)\n\nThis functionality is desired for the proposed seccomp filter patch\nseries. By using PR_SET_NO_NEW_PRIVS, it allows a task to modify the\nsystem call behavior for itself and its child tasks without being\nable to impact the behavior of a more privileged task.\n\nAnother potential use is making certain privileged operations\nunprivileged. For example, chroot may be considered \"safe\" if it cannot\naffect privileged tasks.\n\nNote, this patch causes execve to fail when PR_SET_NO_NEW_PRIVS is\nset and AppArmor is in use. It is fixed in a subsequent patch.\n\nSigned-off-by: Andy Lutomirski \u003cluto@amacapital.net\u003e\nSigned-off-by: Will Drewry \u003cwad@chromium.org\u003e\nAcked-by: Eric Paris \u003ceparis@redhat.com\u003e\nAcked-by: Kees Cook \u003ckeescook@chromium.org\u003e\n\nChange-Id: I2159006d20daefe6add5adc47c22bdbcd7d79e3a\nv18: updated change desc\nv17: using new define values as per 3.4\nSigned-off-by: James Morris \u003cjames.l.morris@oracle.com\u003e\n" }, { "commit": "74cfe2dcc0f4b17f9abbabf349e33c39a260987e", "tree": "206493082f5edc72fdac6c958877090d7d17fb37", "parents": [ "a580da13cb3f1f4984e71befc4f78c5a1f3181d0", "6cf93503105dc0cf63fc1384088db92bb71cbe4c" ], "author": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Tue Dec 16 00:35:23 2014 -0800" }, "committer": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Tue Dec 16 00:35:23 2014 -0800" }, "message": "Merge remote-tracking branch \u0027caf/LA.AF.1.1_rb1.7\u0027 into cm-12.0\n\nConflicts:\n\tdrivers/misc/qseecom.c\n\tfs/proc/task_mmu.c\n\tinclude/net/tcp.h\n\tnet/ipv4/syncookies.c\n\tnet/ipv6/route.c\n\tnet/ipv6/tcp_ipv6.c\n\nChange-Id: I8a953e9f483a24ee45f5e1c570b6a4f92e87c6e9\n" }, { "commit": "45bb5ff6ed69d017d14ec37ef76b27747deed955", "tree": "76e44de5d725dde009ed88d903c1fe4776ebf722", "parents": [ "715fe086a6d99d2efc6276028ac626766567e101", "8ca5b06fa71c0b5ad8174ff1152d3de74e706ee9" ], "author": { "name": "Linux Build Service Account", "email": "lnxbuild@localhost", "time": "Tue Nov 18 00:11:01 2014 -0800" }, "committer": { "name": "Gerrit - the friendly Code Review server", "email": "code-review@localhost", "time": "Tue Nov 18 00:11:01 2014 -0800" }, "message": "Merge \"seq_file: introduce seq_setwidth() and seq_pad()\"" }, { "commit": "7b18590cff07a04fcf955e1648e4a9f11752a545", "tree": "ecb5f439e7001fc162baaa1854bb8211e7cc2690", "parents": [ "50db8c0110dbff94dfacc1f4752a927dbe339e9c" ], "author": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Sun Nov 16 16:48:31 2014 -0800" }, "committer": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Sun Nov 16 17:29:36 2014 -0800" }, "message": "gpu: msm2: Sync to upstream\n\n* Sync to android-msm-3.4-flo-lollipop-release\n\nChange-Id: Ia0df71c0a1f102de034860f4d212a05c806fef7d\n" }, { "commit": "50db8c0110dbff94dfacc1f4752a927dbe339e9c", "tree": "fc604545ec971ab0e224c305f0b948edc08295aa", "parents": [ "25b02b6d180efeec13851162c3319962977c1fb0", "2f64c5e6faa76368cd2c70c1d48fc4c2d44acbbf" ], "author": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Fri Nov 14 01:04:45 2014 -0800" }, "committer": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Fri Nov 14 01:04:45 2014 -0800" }, "message": "Merge remote-tracking branch \u0027caf/caf/LA.AF.1.1_rb1.5\u0027 into cm-12.0\n" }, { "commit": "8c1d434b2e49df7a7cefac06e62ab5faa7eb4776", "tree": "97f3aa4b233011a156128517bd85fb3e09f8cc38", "parents": [ "bc4bcee71617461ed19a852f9d873f5979820ef1", "653be181eef3589b47119cd68c985975119fa61f" ], "author": { "name": "Linux Build Service Account", "email": "lnxbuild@localhost", "time": "Thu Nov 13 13:03:26 2014 -0800" }, "committer": { "name": "Gerrit - the friendly Code Review server", "email": "code-review@localhost", "time": "Thu Nov 13 13:03:26 2014 -0800" }, "message": "Merge \"net: ipv6: autoconf routes into per-device tables\"" }, { "commit": "ad3dae1c0ad772e899815622004f42e1318c48a4", "tree": "ce5d32a7c9d130bac2220a288ad23a4415acdc71", "parents": [ "79fc4d24eef5e4f5e25782690379e97aee0327ea" ], "author": { "name": "Matt Mower", "email": "mowerm@gmail.com", "time": "Sun Oct 05 22:13:10 2014 -0500" }, "committer": { "name": "Matt Mower", "email": "mowerm@gmail.com", "time": "Wed Oct 08 02:18:13 2014 -0500" }, "message": "drivers: net: wireless: add HTC\u0027s bcmdhd_4335_mcc\n\nFrom m7stockui-3.4.10-gef77362.\n\nModifications from stock HTC driver:\n* Remove poorly commented-out CFLAGS section from Makefile\n* Make CONFIG_BCMDHD_4335_MCC select WIRELESS_EXT, WEXT_PRIV\n* Fix msm_watchdog.h include in dhd_sdio.c\n* Our kernel does not need OLD_CFG_80211;

This causes problems for connection managers\nthat want to support multiple simultaneous network connections\nand want control over which one is used by default (e.g., wifi\nand wired).\n\nTo work around this connection managers typically take the routes\nthey prefer and copy them to static routes with low metrics in\nthe main table. This puts the burden on the connection manager\nto watch netlink to see if the routes have changed, delete the\nroutes when their lifetime expires, etc.\n\nInstead, this patch adds a per-interface sysctl to have the\nkernel put autoconf routes into different tables. This allows\neach interface to have its own autoconf table, and choosing the\ndefault interface (or using different interfaces at the same\ntime for different types of traffic) can be done using\nappropriate ip rules.\n\nThe sysctl behaves as follows:\n\n- \u003d 0: default. Put routes into RT6_TABLE_MAIN as before.\n- \u003e 0: manual. Put routes into the specified table.\n- \u003c 0: automatic. Add the absolute value of the sysctl to the\n device\u0027s ifindex, and use that table.\n\nThe automatic mode is most useful in conjunction with\nnet.ipv6.conf.default.accept_ra_rt_table. A connection manager\nor distribution could set it to, say, -100 on boot, and\nthereafter just use IP rules.\n\nChange-Id: I093d39fb06ec413905dc0d0d5792c1bc5d5c73a9\nSigned-off-by: Lorenzo Colitti

1\n\nbusy_factor attribute of a scheduler domain causes busy CPUs (CPUs\nthat are not idle) to load balance less frequently in that domain,\nwhich could impact performance by increasing scheduling latency for\ntasks.\n\nAs an example, consider MC scheduler domain\u0027s attribute values of\nmax_interval \u003d 4ms and busy_factor \u003d 64. Further consider\nmax_load_balance_interval \u003d 100 (HZ/10). In this case, a non-idle CPU\ncould put off load balance check in MC domain by 100ms. This\neffectively means that a CPU running a single task in its queue could\nfail to notice increased load on another CPU (that is in same MC\ndomain) for upto 100ms, before picking up load from the overloaded\nCPU. Needless to say, this leads to increased scheduling latency for\ntasks, affecting performance adversely.\n\nBy setting MC domain\u0027s busy_factor value to 1, we limit maximum\ninterval that busy CPU can put off load balance checks to 4ms\n(effectively 10ms, given HZ value of 100).\n\nChange-Id: Id45869d06f5556ea8eec602b65c2ffd2143fe060\nSigned-off-by: Srivatsa Vaddagiri \u003cvatsa@codeaurora.org\u003e\nSigned-off-by: Syed Rameez Mustafa \u003crameezmustafa@codeaurora.org\u003e\n" }, { "commit": "15d8f1ef6b18f4c96cc5f95fc3acc204deeb2469", "tree": "89967b918b61ea92591630440c2f9384070976d6", "parents": [ "dc223cee085ac3e417b2c614ca9036bca28560fb" ], "author": { "name": "Neil Leeder", "email": "nleeder@codeaurora.org", "time": "Mon Oct 21 17:58:20 2013 -0400" }, "committer": { "name": "Neil Leeder", "email": "nleeder@codeaurora.org", "time": "Mon May 19 15:12:29 2014 -0400" }, "message": "msm: perf: clean up duplicate constraint events\n\nEvents with a duplicate constraint are set to state\u003dOFF when detected,\nso that their duplicate counts are not read.

The priority of these\ntasks is set to 49 by default. If user launches an RT FIFO task\nwith priority lower than 49 of softirq RT tasks, it\u0027s possible\nthere are two RT FIFO tasks enqueued one cpu runqueue at one\nmoment. By current strategy of balancing RT tasks, when it comes\nto RT tasks, we really need to put them off to a CPU that they\ncan run on as soon as possible. Even if it means a bit of cache\nline flushing, we want RT tasks to be run with the least latency.\n\nWhen the user RT FIFO task which just launched before is\nrunning, the sched timer tick of the current cpu happens. In this\ntick period, the timeout value of the user RT task will be\nupdated once. Subsequently, we try to wake up one softirq RT\ntask on its local cpu. As the priority of current user RT task\nis lower than the softirq RT task, the current task will be\npreempted by the higher priority softirq RT task. Before\npreemption, we check to see if current can readily move to a\ndifferent cpu. If so, we will reschedule to allow the RT push logic\nto try to move current somewhere else. Whenever the woken\nsoftirq RT task runs, it first tries to migrate the user FIFO RT\ntask over to a cpu that is running a task of lesser priority. If\nmigration is done, it will send a reschedule request to the found\ncpu by IPI interrupt. Once the target cpu responds the IPI\ninterrupt, it will pick the migrated user RT task to preempt its\ncurrent task. When the user RT task is running on the new cpu,\nthe sched timer tick of the cpu fires. So it will tick the user\nRT task again. This also means the RT task timeout value will be\nupdated again. As the migration may be done in one tick period,\nit means the user RT task timeout value will be updated twice\nwithin one tick.\n\nIf we set a limit on the amount of cpu time for the user RT task\nby setrlimit(RLIMIT_RTTIME), the SIGXCPU signal should be posted\nupon reaching the soft limit.\n\nBut exactly when the SIGXCPU signal should be sent depends on the\nRT task timeout value. In fact the timeout mechanism of sending\nthe SIGXCPU signal assumes the RT task timeout is increased once\nevery tick.\n\nHowever, currently the timeout value may be added twice per\ntick. So it results in the SIGXCPU signal being sent earlier\nthan expected.\n\nTo solve this issue, we prevent the timeout value from increasing\ntwice within one tick time by remembering the jiffies value of\nlast updating the timeout. As long as the RT task\u0027s jiffies is\ndifferent with the global jiffies value, we allow its timeout to\nbe updated.\n\nSigned-off-by: Ying Xue \u003cying.xue@windriver.com\u003e\nSigned-off-by: Fan Du \u003cfan.du@windriver.com\u003e\nReviewed-by: Yong Zhang \u003cyong.zhang0@gmail.com\u003e\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/1342508623-2887-1-git-send-email-ying.xue@windriver.com\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n[ lizf: backported to 3.4: adjust context ]\nSigned-off-by: Li Zefan \u003clizefan@huawei.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n" }, { "commit": "cd1188e7a59ca6c03cab5fe490bf18888a3ca5dc", "tree": "0190e9cc1c4755e196580ebe407525e9b87f715e", "parents": [ "559316545580bbc61cf839e164c8a4c871c6ba42" ], "author": { "name": "AKASHI Takahiro", "email": "takahiro.akashi@linaro.org", "time": "Mon Jan 13 13:33:09 2014 -0800" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Thu Feb 13 11:51:08 2014 -0800" }, "message": "audit: correct a type mismatch in audit_syscall_exit()\n\ncommit 06bdadd7634551cfe8ce071fe44d0311b3033d9e upstream.\n\naudit_syscall_exit() saves a result of regs_return_value() in intermediate\n\"int\" variable and passes it to __audit_syscall_exit(), which expects its\nsecond argument as a \"long\" value.

27c73ae759774e63313c1fbfeb17ba076cea64c5 upstream.\n\nCommit 7cb2ef56e6a8 (\"mm: fix aio performance regression for database\ncaused by THP\") can cause dereference of a dangling pointer if\nsplit_huge_page runs during PageHuge() if there are updates to the\ntail_page-\u003eprivate field.\n\nAlso it is repeating compound_head twice for hugetlbfs and it is running\ncompound_head+compound_trans_head for THP when a single one is needed in\nboth cases.\n\nThe new code within the PageSlab() check doesn\u0027t need to verify that the\nTHP page size is never bigger than the smallest hugetlbfs page size, to\navoid memory corruption.\n\nA longstanding theoretical race condition was found while fixing the\nabove (see the change right after the skip_unlock label, that is\nrelevant for the compound_lock path too).\n\nBy re-establishing the _mapcount tail refcounting for all compound\npages, this also fixes the below problem:\n\n echo 0

For Eric, the problem was\nthat page-\u003epfmemalloc was not being cleared for captured pages leading\nto a poor interaction with swap-over-NFS support causing the packets to\nbe dropped. However, I identified a few more problems with the patch\nincluding the fact that it can increase contention on zone-\u003elock in some\ncases which could result in async direct compaction being aborted early.\n\nIn retrospect the capture patch took the wrong approach. What it should\nhave done is mark the pageblock being migrated as MIGRATE_ISOLATE if it\nwas allocating for THP and avoided races that way. While the patch was\nshowing to improve allocation success rates at the time, the benefit is\nmarginal given the relative complexity and it should be revisited from\nscratch in the context of the other reclaim-related changes that have\ntaken place since the patch was first written and tested.

This\ninformation is not cleared by the page allocator based on activity due to\nthe impact it would have to the page allocator fast paths. Hence there is\na requirement that something clear the cache or pageblocks will be skipped\nforever. Currently the cache is cleared if there were a number of recent\nallocation failures and it has not been cleared within the last 5 seconds.\nTime-based decisions like this are terrible as they have no relationship\nto VM activity and is basically a big hammer.\n\nUnfortunately, accurate heuristics would add cost to some hot paths so\nthis patch implements a rough heuristic. There are two cases where the\ncache is cleared.\n\n1. If a !kswapd process completes a compaction cycle (migrate and free\n scanner meet), the zone is marked compact_blockskip_flush. When kswapd\n goes to sleep, it will clear the cache. This is expected to be the\n common case where the cache is cleared. It does not really matter if\n kswapd happens to be asleep or going to sleep when the flag is set as\n it will be woken on the next allocation request.\n\n2. If there have been multiple failures recently and compaction just\n finished being deferred then a process will clear the cache and start a\n full scan. This situation happens if there are multiple high-order\n allocation requests under heavy memory pressure.\n\nThe clearing of the PG_migrate_skip bits and other scans is inherently\nracy but the race is harmless. For allocations that can fail such as THP,\nthey will simply fail. For requests that cannot fail, they will retry the\nallocation. Tests indicated that scanning rates were roughly similar to\nwhen the time-based heuristic was used and the allocation success rates\nwere similar.\n\nChange-Id: If690ae126badb9f9cc5632e9ffb9d376bf210fb0\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Richard Davies \u003crichard@arachsys.com\u003e\nCc: Shaohua Li \u003cshli@kernel.org\u003e\nCc: Avi Kivity \u003cavi@redhat.com\u003e\nCc: Rafael Aquini \u003caquini@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nGit-commit: 62997027ca5b3d4618198ed8b1aba40b61b1137b\nGit-repo: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git\nSigned-off-by: Laura Abbott \u003clauraa@codeaurora.org\u003e\n" }, { "commit": "cc5a88ab9e86f9dc022020b2d90b8d51bc80c932", "tree": "953b699613758962008aa7e7fba4945005d22fea", "parents": [ "d6ed972cf5323c04dd622330da80eb255a4b6aad" ], "author": { "name": "Mel Gorman", "email": "mgorman@suse.de", "time": "Mon Oct 08 16:32:41 2012 -0700" }, "committer": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Fri Jan 17 22:12:18 2014 -0800" }, "message": "mm: compaction: cache if a pageblock was scanned and no pages were isolated\n\nWhen compaction was implemented it was known that scanning could\npotentially be excessive. The ideal was that a counter be maintained for\neach pageblock but maintaining this information would incur a severe\npenalty due to a shared writable cache line. It has reached the point\nwhere the scanning costs are a serious problem, particularly on\nlong-lived systems where a large process starts and allocates a large\nnumber of THPs at the same time.\n\nInstead of using a shared counter, this patch adds another bit to the\npageblock flags called PG_migrate_skip. If a pageblock is scanned by\neither migrate or free scanner and 0 pages were isolated, the pageblock is\nmarked to be skipped in the future. When scanning, this bit is checked\nbefore any scanning takes place and the block skipped if set.\n\nThe main difficulty with a patch like this is \"when to ignore the cached\ninformation?\" If it\u0027s ignored too often, the scanning rates will still be\nexcessive. If the information is too stale then allocations will fail\nthat might have otherwise succeeded. In this patch\n\no CMA always ignores the information\no If the migrate and free scanner meet then the cached information will\n be discarded if it\u0027s at least 5 seconds since the last time the cache\n was discarded\no If there are a large number of allocation failures, discard the cache.\n\nThe time-based heuristic is very clumsy but there are few choices for a\nbetter event. Depending solely on multiple allocation failures still\nallows excessive scanning when THP allocations are failing in quick\nsuccession due to memory pressure. Waiting until memory pressure is\nrelieved would cause compaction to continually fail instead of using\nreclaim/compaction to try allocate the page. The time-based mechanism is\nclumsy but a better option is not obvious.\n\nChange-Id: I17a4887aca9bb3d2d9d3756089ad7c9b89922727\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\nAcked-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Richard Davies \u003crichard@arachsys.com\u003e\nCc: Shaohua Li \u003cshli@kernel.org\u003e\nCc: Avi Kivity \u003cavi@redhat.com\u003e\nAcked-by: Rafael Aquini \u003caquini@redhat.com\u003e\nCc: Fengguang Wu \u003cfengguang.wu@intel.com\u003e\nCc: Michal Nazarewicz \u003cmina86@mina86.com\u003e\nCc: Bartlomiej Zolnierkiewicz \u003cb.zolnierkie@samsung.com\u003e\nCc: Kyungmin Park \u003ckyungmin.park@samsung.com\u003e\nCc: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nGit-commit: bb13ffeb9f6bfeb301443994dfbf29f91117dfb3\nGit-repo: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git\n[lauraa@codeaurora.org: Context fixup due to merging patches out of order]\nSigned-off-by: Laura Abbott \u003clauraa@codeaurora.org\u003e\n" }, { "commit": "c74068b68d00e36755ce5927bce33d62f1e4edd3", "tree": "a11cd4f023568a2506ab5b26cc0a1014ff88f54b", "parents": [ "bc337a9d96c709c7f4602368eb77401c914ac948" ], "author": { "name": "Mel Gorman", "email": "mgorman@suse.de", "time": "Mon Oct 08 16:29:12 2012 -0700" }, "committer": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Fri Jan 17 22:12:17 2014 -0800" }, "message": "mm: compaction: capture a suitable high-order page immediately when it is made available\n\nWhile compaction is migrating pages to free up large contiguous blocks\nfor allocation it races with other allocation requests that may steal\nthese blocks or break them up.

If ti-\u003etype-\u003estatus returns non-zero,\nretrieve_status assumes that the buffer overflowed and sets\nDM_BUFFER_FULL_FLAG.\n\nHowever, targets don\u0027t return non-zero values from their status method\non overflow. Most targets returns always zero.\n\nIf a buffer overflow happens in a target that is not the last in the\ntable, it gets noticed during the next iteration of the loop in\nretrieve_status; but if a buffer overflow happens in the last target, it\ngoes unnoticed and erroneously truncated data is returned.\n\nIn the current code, the targets behave in the following way:\n* dm-crypt returns -ENOMEM if there is not enough space to store the\n key, but it returns 0 on all other overflows.\n* dm-thin returns errors from the status method if a disk error happened.\n This is incorrect because retrieve_status doesn\u0027t check the error\n code, it assumes that all non-zero values mean buffer overflow.\n* all the other targets always return 0.\n\nThis patch changes the ti-\u003etype-\u003estatus function to return void (because\nmost targets don\u0027t use the return code). Overflow is detected in\nretrieve_status: if the status method fills up the remaining space\ncompletely, it is assumed that buffer overflow happened.\n\nSigned-off-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n" }, { "commit": "18719a4c7a90af3de4bb071511dd4a6dcf61a2e0", "tree": "8a2a831db542446ee13ec1d9ec8d484ecbb72843", "parents": [ "11afb94fbe0337a06ee7fce36841969b4e538622" ], "author": { "name": "Hannes Frederic Sowa", "email": "hannes@stressinduktion.org", "time": "Thu Nov 21 03:14:22 2013 +0100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Sun Dec 08 07:29:41 2013 -0800" }, "message": "net: rework recvmsg handler msg_name and msg_namelen logic\n\n[ Upstream commit f3d3342602f8bcbf37d7c46641cb9bca7618eb1c ]\n\nThis patch now always passes msg-\u003emsg_namelen as 0. recvmsg handlers must\nset msg_namelen to the proper size \u003c\u003d sizeof(struct sockaddr_storage)\nto return msg_name to the user.\n\nThis prevents numerous uninitialized memory leaks we had in the\nrecvmsg handlers and makes it harder for new code to accidentally leak\nuninitialized memory.\n\nOptimize for the case recvfrom is called with NULL as address. We don\u0027t\nneed to copy the address at all, so set it to NULL before invoking the\nrecvmsg handler. We can do so, because all the recvmsg handlers must\ncope with the case a plain read() is called on them. read() also sets\nmsg_name to NULL.\n\nAlso document these changes in include/linux/net.h as suggested by David\nMiller.\n\nChanges since RFC:\n\nSet msg-\u003emsg_name \u003d NULL if user specified a NULL in msg_name but had a\nnon-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn\u0027t\naffect sendto as it would bail out earlier while trying to copy-in the\naddress. It also more naturally reflects the logic by the callers of\nverify_iovec.\n\nWith this change in place I could remove \"\nif (!uaddr || msg_sys-\u003emsg_namelen \u003d\u003d 0)\n\tmsg-\u003emsg_name \u003d NULL\n\".\n\nThis change does not alter the user visible error logic as we ignore\nmsg_namelen as long as msg_name is NULL.\n\nAlso remove two unnecessary curly brackets in ___sys_recvmsg and change\ncomments to netdev style.\n\nCc: David Miller \u003cdavem@davemloft.net\u003e\nSuggested-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: Hannes Frederic Sowa \u003channes@stressinduktion.org\u003e\nSigned-off-by: David S.
