Instead, we need it to return whether\nthe underlying flash device can have bad eraseblocks or not.  UBI needs\nthis information because it affects how it handles the underlying flash.\nE.g., if the underlying flash is NOR, it cannot have bad blocks and any\nwrite or erase error is fatal, and all we can do is to switch to R/O\nmode.  We do not need to reserve a pool of good eraseblocks for bad\neraseblocks handling, and so on.\n\nThis patch also removes \u0027mtd_can_have_bb()\u0027 invocations from Logfs to\nensure correct Logfs behavior.\n\nI\u0027ve tested that with this patch UBI works on top of NOR and NAND\nflashes emulated by mtdram and nandsim correspondingly.\n\nThis patch is based on patch from Linus Torvalds.\n\nSigned-off-by: Artem Bityutskiy \u003cartem.bityutskiy@linux.intel.com\u003e\nAcked-by: Jörn Engel \u003cjoern@logfs.org\u003e\nAcked-by: Prasad Joshi \u003cprasadjoshi.linux@gmail.com\u003e\nAcked-by: Brian Norris \u003ccomputersforpeace@gmail.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

But that also means that now \"mtd_can_have_bb()\"\nalways returns 0.\n\nNow, \"mtd_block_markbad()\" will obviously return an error if the\nlow-level driver doesn\u0027t support bad blocks, so this is somewhat\nnon-symmetric, but it actually makes sense if a NULL \"block_isbad\"\nfunction is considered to mean \"I assume that all my blocks are always\ngood\".\n"

It keeps track of erase\ncount, level etc. for every segment.\n\nBad things happen with a segment belonging to the segment file is GCed\n\n ------------[ cut here ]------------\nkernel BUG at /home/prasad/logfs/readwrite.c:297!\ninvalid opcode: 0000 [#1] SMP\nModules linked in: logfs joydev usbhid hid psmouse e1000 i2c_piix4\n\t\tserio_raw [last unloaded: logfs]\nPid: 20161, comm: mount Not tainted 3.1.0-rc3+ #3 innotek GmbH\n\t\tVirtualBox\nEIP: 0060:[\u003cf809132a\u003e] EFLAGS: 00010292 CPU: 0\nEIP is at logfs_lock_write_page+0x6a/0x70 [logfs]\nEAX: 00000027 EBX: f73f5b20 ECX: c16007c8 EDX: 00000094\nESI: 00000000 EDI: e59be6e4 EBP: c7337b28 ESP: c7337b18\nDS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068\nProcess mount (pid: 20161, ti\u003dc7336000 task\u003deb323f70 task.ti\u003dc7336000)\nStack:\nf8099a3d c7337b24 f73f5b20 00001002 c7337b50 f8091f6d f8099a4d f80994e4\n00000003 00000000 c7337b68 00000000 c67e4400 00001000 c7337b80 f80935e5\n00000000 00000000 00000000 00000000 e1fcf000 0000000f e59be618 c70bf900\nCall Trace:\n[\u003cf8091f6d\u003e] logfs_get_write_page.clone.16+0xdd/0x100 [logfs]\n[\u003cf80935e5\u003e] logfs_mod_segment_entry+0x55/0x110 [logfs]\n[\u003cf809460d\u003e] logfs_get_segment_entry+0x1d/0x20 [logfs]\n[\u003cf8091060\u003e] ? logfs_cleanup_journal+0x50/0x50 [logfs]\n[\u003cf809521b\u003e] ostore_get_erase_count+0x1b/0x40 [logfs]\n[\u003cf80965b8\u003e] logfs_open_area+0xc8/0x150 [logfs]\n[\u003cc141a7ec\u003e] ? kmemleak_alloc+0x2c/0x60\n[\u003cf809668e\u003e] __logfs_segment_write.clone.16+0x4e/0x1b0 [logfs]\n[\u003cc10dd563\u003e] ? mempool_kmalloc+0x13/0x20\n[\u003cc10dd563\u003e] ? mempool_kmalloc+0x13/0x20\n[\u003cf809696f\u003e] logfs_segment_write+0x17f/0x1d0 [logfs]\n[\u003cf8092e8c\u003e] logfs_write_i0+0x11c/0x180 [logfs]\n[\u003cf8092f35\u003e] logfs_write_direct+0x45/0x90 [logfs]\n[\u003cf80934cd\u003e] __logfs_write_buf+0xbd/0xf0 [logfs]\n[\u003cc102900e\u003e] ? kmap_atomic_prot+0x4e/0xe0\n[\u003cf809424b\u003e] logfs_write_buf+0x3b/0x60 [logfs]\n[\u003cf80947a9\u003e] __logfs_write_inode+0xa9/0x110 [logfs]\n[\u003cf8094cb0\u003e] logfs_rewrite_block+0xc0/0x110 [logfs]\n[\u003cf8095300\u003e] ? get_mapping_page+0x10/0x60 [logfs]\n[\u003cf8095aa0\u003e] ? logfs_load_object_aliases+0x2e0/0x2f0 [logfs]\n[\u003cf808e57d\u003e] logfs_gc_segment+0x2ad/0x310 [logfs]\n[\u003cf808e62a\u003e] __logfs_gc_once+0x4a/0x80 [logfs]\n[\u003cf808ed43\u003e] logfs_gc_pass+0x683/0x6a0 [logfs]\n[\u003cf8097a89\u003e] logfs_mount+0x5a9/0x680 [logfs]\n[\u003cc1126b21\u003e] mount_fs+0x21/0xd0\n[\u003cc10f6f6f\u003e] ? __alloc_percpu+0xf/0x20\n[\u003cc113da41\u003e] ? alloc_vfsmnt+0xb1/0x130\n[\u003cc113db4b\u003e] vfs_kern_mount+0x4b/0xa0\n[\u003cc113e06e\u003e] do_kern_mount+0x3e/0xe0\n[\u003cc113f60d\u003e] do_mount+0x34d/0x670\n[\u003cc10f2749\u003e] ? strndup_user+0x49/0x70\n[\u003cc113fcab\u003e] sys_mount+0x6b/0xa0\n[\u003cc142d87c\u003e] syscall_call+0x7/0xb\nCode: f8 e8 8b 93 39 c9 8b 45 f8 3e 0f ba 28 00 19 d2 85 d2 74 ca eb d0 0f 0b 8d 45 fc 89 44 24 04 c7 04 24 3d 9a 09 f8 e8 09 92 39 c9 \u003c0f\u003e 0b 8d 74 26 00 55 89 e5 3e 8d 74 26 00 8b 10 80 e6 01 74 09\nEIP: [\u003cf809132a\u003e] logfs_lock_write_page+0x6a/0x70 [logfs] SS:ESP 0068:c7337b18\n---[ end trace 96e67d5b3aa3d6ca ]---\n\nThe patch passes locked page to __logfs_write_inode.

It makes the allocator ignore CHUNK_ALLOC_FORCE If someone\nsets -\u003eforce_alloc to CHUNK_ALLOC_LIMITED, and makes the enospc error happen.\n\nFix these two wrong checks. Especially the second one, we fix it by changing\nthe value of CHUNK_ALLOC_LIMITED and CHUNK_ALLOC_FORCE, and make\nCHUNK_ALLOC_FORCE greater than CHUNK_ALLOC_LIMITED since CHUNK_ALLOC_FORCE has\nhigher priority. And if the value which is passed in by the caller is greater\nthan -\u003eforce_alloc, use the passed value.\n\nSigned-off-by: Miao Xie \u003cmiaox@cn.fujitsu.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n"

      "message": "eCryptfs: Check inode changes in setattr\n\nMost filesystems call inode_change_ok() very early in -\u003esetattr(), but\neCryptfs didn\u0027t call it at all. It allowed the lower filesystem to make\nthe call in its -\u003esetattr() function. Then, eCryptfs would copy the\nappropriate inode attributes from the lower inode to the eCryptfs inode.\n\nThis patch changes that and actually calls inode_change_ok() on the\neCryptfs inode, fairly early in ecryptfs_setattr(). Ideally, the call\nwould happen earlier in ecryptfs_setattr(), but there are some possible\ninode initialization steps that must happen first.\n\nSince the call was already being made on the lower inode, the change in\nfunctionality should be minimal, except for the case of a file extending\ntruncate call. In that case, inode_newsize_ok() was never being\ncalled on the eCryptfs inode. Rather than inode_newsize_ok() catching\nmaximum file size errors early on, eCryptfs would encrypt zeroed pages\nand write them to the lower filesystem until the lower filesystem\u0027s\nwrite path caught the error in generic_write_checks(). This patch\nintroduces a new function, called ecryptfs_inode_newsize_ok(), which\nchecks if the new lower file size is within the appropriate limits when\nthe truncate operation will be growing the lower file.\n\nIn summary this change prevents eCryptfs truncate operations (and the\nresulting page encryptions), which would exceed the lower filesystem\nlimits or FSIZE rlimits, from ever starting.\n\nSigned-off-by: Tyler Hicks \u003ctyhicks@canonical.com\u003e\nReviewed-by: Li Wang \u003cliwang@nudt.edu.cn\u003e\nCc: \u003cstable@vger.kernel.org\u003e\n"

Since the\nvectors page is required for handling faults, clearing the YOUNG bit (and\nsubsequently writing a faulting pte) means that we lose the vectors page\n*globally* and cannot fault it back in.  This results in a system deadlock\non the next exception.\n\nTo see this problem in action, just run:\n\n\t$ echo 1 \u003e /proc/self/clear_refs\n\non an ARM platform (as any user) and watch your system hang.  I think this\nhas been the case since 2.6.37\n\nThis patch avoids clearing the aforementioned bits for reserved pages,\ntherefore leaving the vectors page intact on ARM.  Since reserved pages\nare not candidates for swap, this change should not have any impact on the\nusefulness of clear_refs.\n\nSigned-off-by: Will Deacon \u003cwill.deacon@arm.com\u003e\nReported-by: Moussa Ba \u003cmoussaba@micron.com\u003e\nAcked-by: Hugh Dickins \u003chughd@google.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nAcked-by: Nicolas Pitre \u003cnico@linaro.org\u003e\nCc: Matt Mackall \u003cmpm@selenic.com\u003e\nCc: \u003cstable@vger.kernel.org\u003e\t\t[2.6.37+]\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "proc: clean up and fix /proc/\u003cpid\u003e/mem handling\n\nJüri Aedla reported that the /proc/\u003cpid\u003e/mem handling really isn\u0027t very\nrobust, and it also doesn\u0027t match the permission checking of any of the\nother related files.\n\nThis changes it to do the permission checks at open time, and instead of\ntracking the process, it tracks the VM at the time of the open.  That\nsimplifies the code a lot, but does mean that if you hold the file\ndescriptor open over an execve(), you\u0027ll continue to read from the _old_\nVM.\n\nThat is different from our previous behavior, but much simpler.  If\nsomebody actually finds a load where this matters, we\u0027ll need to revert\nthis commit.\n\nI suspect that nobody will ever notice - because the process mapping\naddresses will also have changed as part of the execve.  So you cannot\nactually usefully access the fd across a VM change simply because all\nthe offsets for IO would have changed too.\n\nReported-by: Jüri Aedla \u003casd@ut.ee\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "audit: only allow tasks to set their loginuid if it is -1\n\nAt the moment we allow tasks to set their loginuid if they have\nCAP_AUDIT_CONTROL.  In reality we want tasks to set the loginuid when they\nlog in and it be impossible to ever reset.  We had to make it mutable even\nafter it was once set (with the CAP) because on update and admin might have\nto restart sshd.  Now sshd would get his loginuid and the next user which\nlogged in using ssh would not be able to set his loginuid.\n\nSystemd has changed how userspace works and allowed us to make the kernel\nwork the way it should.  With systemd users (even admins) are not supposed\nto restart services directly.  The system will restart the service for\nthem.  Thus since systemd is going to loginuid\u003d\u003d-1, sshd would get -1, and\nsshd would be allowed to set a new loginuid without special permissions.\n\nIf an admin in this system were to manually start an sshd he is inserting\nhimself into the system chain of trust and thus, logically, it\u0027s his\nloginuid that should be used!  Since we have old systems I make this a\nKconfig option.\n\nSigned-off-by: Eric Paris \u003ceparis@redhat.com\u003e\n"
