The LFS\n experience suggests not lying and returning an error code might be\n better, but the historical precedent with uids is different and I\n can not think of anything that would break by lying about a uid we\n can\u0027t map.\n\n - Capabilities are localized to the current user namespace making it\n safe to give the initial user in a user namespace all capabilities.\n\n My git tree covers all of the modifications needed to convert the core\n kernel and enough changes to make a system bootable to runlevel 1.\"\n\nFix up trivial conflicts due to nearby independent changes in fs/stat.c\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (46 commits)\n userns: Silence silly gcc warning.\n cred: use correct cred accessor with regards to rcu read lock\n userns: Convert the move_pages, and migrate_pages permission checks to use uid_eq\n userns: Convert cgroup permission checks to use uid_eq\n userns: Convert tmpfs to use kuid and kgid where appropriate\n userns: Convert sysfs to use kgid/kuid where appropriate\n userns: Convert sysctl permission checks to use kuid and kgids.\n userns: Convert proc to use kuid/kgid where appropriate\n userns: Convert ext4 to user kuid/kgid where appropriate\n userns: Convert ext3 to use kuid/kgid where appropriate\n userns: Convert ext2 to use kuid/kgid where appropriate.\n userns: Convert devpts to use kuid/kgid where appropriate\n userns: Convert binary formats to use kuid/kgid where appropriate\n userns: Add negative depends on entries to avoid building code that is userns unsafe\n userns: signal remove unnecessary map_cred_ns\n userns: Teach inode_capable to understand inodes whose uids map to other namespaces.\n userns: Fail exec for suid and sgid binaries with ids outside our user namespace.\n userns: Convert stat to return values mapped from kuids and kgids\n userns: Convert user specfied uids and gids in chown into kuids and kgid\n userns: Use uid_eq gid_eq helpers when comparing kuids and kgids in the vfs\n ...\n" }, { "commit": "269af9a1a08d368b46d72e74126564d04c354f7e", "tree": "f0f2a8dd54075edebbb728602822e2b7378588d0", "parents": [ "8ca038dc10eec80f280d9d483f1835ac2763a787", "8b5ad472991796b2347464922c72de2ca5a028f3" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 23 10:44:35 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 23 10:44:35 2012 -0700" }, "message": "Merge branch \u0027x86-extable-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip\n\nPull exception table generation updates from Ingo Molnar:\n \"The biggest change here is to allow the build-time sorting of the\n exception table, to speed up booting.

Posted to LKML:\n https://lkml.org/lkml/2012/4/23/322.\n\n 3) A couple of commits that improve the efficiency of the interaction\n between preemptible RCU and the scheduler, these two being all that\n survived an abortive attempt to allow preemptible RCU\u0027s\n __rcu_read_lock() to be inlined. The full set was posted to LKML at\n https://lkml.org/lkml/2012/4/14/143, and the first and third patches\n of that set remain.\n\n 4) Lai Jiangshan\u0027s algorithmic implementation of SRCU, which includes\n call_srcu() and srcu_barrier().

This was\nneeded to reduce lock contention that was induced by the synchronization\nof scheduling-clock interrupts, which was in turn needed to improve\nenergy efficiency for moderate-sized lightly loaded servers.\n\nHowever, reducing the leaf-level fanout means that there are more\nleaf-level rcu_node structures in the tree, which in turn means that\nRCU\u0027s grace-period initialization incurs more cache misses. This is\nnot a problem on moderate-sized servers with only a few tens of CPUs,\nbut becomes a major source of real-time latency spikes on systems with\nmany hundreds of CPUs.

Therefore,\nthese systems need maximal values for the rcu_node leaf-level fanout.\n\nThis commit addresses this problem by introducing a new kernel parameter\nnamed RCU_FANOUT_LEAF that directly controls the leaf-level fanout.\nThis parameter defaults to 16 to handle the common case of a moderate\nsized lightly loaded servers, but may be set higher on larger systems.\n\nReported-by: Mike Galbraith \u003cefault@gmx.de\u003e\nReported-by: Dimitri Sivanich \u003csivanich@sgi.com\u003e\nSigned-off-by: Paul E.

It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here.

Thanks\n Mahesh Salgaonkar.\n\n - The \"EEH\" code (pSeries PCI error handling \u0026 recovery) got a big\n spring cleaning, motivated by the need to be able to implement a\n new backend for it on top of some new different type of firwmare.\n\n The work isn\u0027t complete yet, but a good chunk of the cleanups is\n there. Note that this adds a field to struct device_node which is\n not very nice and which Grant objects to. I will have a patch soon\n that moves that to a powerpc private data structure (hopefully\n before rc1) and we\u0027ll improve things further later on (hopefully\n getting rid of the need for that pointer completely). Thanks Gavin\n Shan.\n\n - I dug into our exception \u0026 interrupt handling code to improve the\n way we do lazy interrupt handling (and make it work properly with\n \"edge\" triggered interrupt sources), and while at it found \u0026 fixed\n a wagon of issues in those areas, including adding support for page\n fault retry \u0026 fatal signals on page faults.\n\n - Your usual random batch of

The implementation was based off the structure of the\nMIPS platform and information in this\n(http://lists.fedoraproject.org/pipermail/arm/2009-October/000382.html)\nmailing list thread. The required audit_syscall_exit and\naudit_syscall_entry checks were added to ptrace using the standard\nregisters for system call values (r0 through r3). A thread information\nflag was added for auditing (TIF_SYSCALL_AUDIT) and a meta-flag was\nadded (_TIF_SYSCALL_WORK) to simplify modifications to the syscall\nentry/exit. Now, if either the TRACE flag is set or the AUDIT flag is\nset, the syscall_trace function will be executed. The prober changes\nwere made to Kconfig to allow CONFIG_AUDITSYSCALL to be enabled.\n\nDue to platform availability limitations, this patch was only tested\non the Android platform running the modified \"android-goldfish-2.6.29\"\nkernel. A test compile was performed using Code Sourcery\u0027s\ncross-compilation toolset and the current linux-3.0 stable kernel. The\nchanges compile without error.

The delay was longer than the timeouts used in\nthe NFS client during mounting.\n\nNFSROOT worked for Lukas before commit 56463e50 because in those\nkernels, the client\u0027s first operation was an rpcbind request to\ndetermine which port the NFS server was listening on. When that\nrequest failed after a long timeout, the client simply selected the\ndefault NFS port (2049). By that time the switch was allowing access\nto the LAN, and the mount succeeded.\n\nNeither of these client behaviors is desirable, so reverting 56463e50\nis really not a choice. Instead, introduce a mechanism that retries\nthe NFSROOT mount request several times.
