2012-01-05nfs: fix regression in handling of context= option in NFSv4Jeff Layton
Setting the security context of a NFSv4 mount via the context= mount option is currently broken. The NFSv4 codepath allocates a parsed options struct, and then parses the mount options to fill it. It eventually calls nfs4_remote_mount which calls security_init_mnt_opts. That clobbers the lsm_opts struct that was populated earlier. This bug also looks like it causes a small memory leak on each v4 mount where context= is used. Fix this by moving the initialization of the lsm_opts into nfs_alloc_parsed_mount_data. Also, add a destructor for nfs_parsed_mount_data to make it easier to free all of the allocations hanging off of it, and to ensure that the security_free_mnt_opts is called whenever security_init_mnt_opts is. I believe this regression was introduced quite some time ago, probably by commit c02d7adf.

2012-01-05NFS - fix recent breakage to NFS error handling.NeilBrown
From c6d615d2b97fe305cbf123a8751ced859dca1d5e Mon Sep 17 00:00:00 2001 From: NeilBrown <neilb@suse.de> Date: Wed, 16 Nov 2011 09:39:05 +1100 Subject: [PATCH] NFS - fix recent breakage to NFS error handling. commit 02c24a82187d5a628c68edfe71ae60dc135cd178 made a small and presumably unintended change to write error handling in NFS. Previously an error from filemap_write_and_wait_range would only be of interest if nfs_file_fsync did not return an error. After this commit, an error from filemap_write_and_wait_range would mean that (the rest of) nfs_file_fsync would not even be called. This means that: 1/ you are more likely to see EIO than e.g. EDQUOT or ENOSPC. 2/ NFS_CONTEXT_ERROR_WRITE remains set for longer so more writes are synchronous. This patch restores previous behaviour.

2012-01-05NFS: Retry mounting NFSROOTChuck Lever
Lukas Razik <linux@razik.name> reports that on his SPARC system, booting with an NFS root file system stopped working after commit 56463e50 "NFS: Use super.c for NFSROOT mount option parsing." We found that the network switch to which Lukas' client was attached was delaying access to the LAN after the client's NIC driver reported that its link was up. The delay was longer than the timeouts used in the NFS client during mounting. NFSROOT worked for Lukas before commit 56463e50 because in those kernels, the client's first operation was an rpcbind request to determine which port the NFS server was listening on. When that request failed after a long timeout, the client simply selected the default NFS port (2049). By that time the switch was allowing access to the LAN, and the mount succeeded. Neither of these client behaviors is desirable, so reverting 56463e50 is really not a choice. Instead, introduce a mechanism that retries the NFSROOT mount request several times. This is the same tactic that normal user space NFS mounts employ to overcome server and network delays.

2012-01-04ptrace: ensure JOBCTL_STOP_SIGMASK is not zero after detachOleg Nesterov
This is the temporary simple fix for 3.2, we need more changes in this area. 1. do_signal_stop() assumes that the running untraced thread in the stopped thread group is not possible. This was our goal but it is not yet achieved: a stopped-but-resumed tracee can clone the running thread which can initiate another group-stop. Remove WARN_ON_ONCE(!current->ptrace). 2. A new thread always starts with ->jobctl = 0. If it is auto-attached and this group is stopped, __ptrace_unlink() sets JOBCTL_STOP_PENDING but JOBCTL_STOP_SIGMASK part is zero, this triggers WANR_ON(!signr) in do_jobctl_trap() if another debugger attaches. Change __ptrace_unlink() to set the artificial SIGSTOP for report. Alternatively we could change ptrace_init_task() to copy signr from current, but this means we can copy it for no reason and hide the possible similar problems.

2012-01-04ptrace: partially fix the do_wait(WEXITED) vs EXIT_DEAD->EXIT_ZOMBIE raceOleg Nesterov
Test-case: int main(void) { int pid, status; pid = fork(); if (!pid) { for (;;) { if (!fork()) return 0; if (waitpid(-1, &status, 0) < 0) { printf("ERR!! wait: %m\n"); return 0; } } } assert(ptrace(PTRACE_ATTACH, pid, 0,0) == 0); assert(waitpid(-1, NULL, 0) == pid); assert(ptrace(PTRACE_SETOPTIONS, pid, 0, PTRACE_O_TRACEFORK) == 0); do { ptrace(PTRACE_CONT, pid, 0, 0); pid = waitpid(-1, NULL, 0); } while (pid > 0); return 1; } It fails because ->real_parent sees its child in EXIT_DEAD state while the tracer is going to change the state back to EXIT_ZOMBIE in wait_task_zombie(). The offending commit is 823b018e which moved the EXIT_DEAD check, but in fact we should not blame it. The original code was not correct as well because it didn't take ptrace_reparented() into account and because we can't really trust ->ptrace. This patch adds the additional check to close this particular race but it doesn't solve the whole problem. We simply can't rely on ->ptrace in this case, it can be cleared if the tracer is multithreaded by the exiting ->parent. I think we should kill EXIT_DEAD altogether, we should always remove the soon-to-be-reaped child from ->children or at least we should never do the DEAD->ZOMBIE transition. But this is too complex for 3.2.

2012-01-04Revert "rtc: Expire alarms after the time is set."Linus Torvalds
This reverts commit 93b2ec0128c431148b216b8f7337c1a52131ef03. The call to "schedule_work()" in rtc_initialize_alarm() happens too early, and can cause oopses at bootup Neil Brown explains why we do it: "If you set an alarm in the future, then shutdown and boot again after that time, then you will end up with a timer_queue node which is in the past. When this happens the queue gets stuck. That entry-in-the-past won't get removed until and interrupt happens and an interrupt won't happen because the RTC only triggers an interrupt when the alarm is "now". So you'll find that e.g. "hwclock" will always tell you that 'select' timed out. So we force the interrupt work to happen at the start just in case." and has a patch that convert it to do things in-process rather than with the worker thread, but right now it's too late to play around with this, so we just revert the patch that caused problems for now.

This bug has been around for a long time, but the fact that we used to cap the clients MaxBufferSize at the same level as the server tended to paper over it.

2012-01-04security: Fix security_old_inode_init_security() when CONFIG_SECURITY is not setJan Kara
Commit 1e39f384bb01 ("evm: fix build problems") makes the stub version of security_old_inode_init_security() return 0 when CONFIG_SECURITY is not set. But that makes callers such as reiserfs_security_init() assume that security_old_inode_init_security() has set name, value, and len arguments properly - but security_old_inode_init_security() left them uninitialized which then results in interesting failures. Revert security_old_inode_init_security() to the old behavior of returning EOPNOTSUPP since both callers (reiserfs and ocfs2) handle this just fine. [ Also fixed the S_PRIVATE(inode) case of the actual non-stub security_old_inode_init_security() function to return EOPNOTSUPP for the same reason, as pointed out by Mimi Zohar. It got incorrectly changed to match the new function in commit fb88c2b6cbb1: "evm: fix security/security_old_init_security return code". - Linus ] Reported-by: Jorge Bastos <mysql.jorge@decimal.pt> Acked-by: James Morris <jmorris@namei.org> Acked-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-12-31futex: Fix uninterruptible loop due to gate_areaHugh Dickins
It was found (by Sasha) that if you use a futex located in the gate area we get stuck in an uninterruptible infinite loop, much like the ZERO_PAGE issue. While looking at this problem, PeterZ realized you'll get into similar trouble when hitting any install_special_pages() mapping. And are there still drivers setting up their own special mmaps without page->mapping, and without special VM or pte flags to make get_user_pages fail? In most cases, if page->mapping is NULL, we do not need to retry at all: Linus points out that even /proc/sys/vm/drop_caches poses no problem, because it ends up using remove_mapping(), which takes care not to interfere when the page reference count is raised. But there is still one case which does need a retry: if memory pressure called shmem_writepage in between get_user_pages_fast dropping page table lock and our acquiring page lock, then the page gets switched from filecache to swapcache (and ->mapping set to NULL) whatever the refcount. Fault it back in to get the page->mapping needed for key->shared.inode.

2011-12-30procfs: do not confuse jiffies with cputime64_tAndreas Schwab
Commit 2a95ea6c0d129b4 ("procfs: do not overflow get_{idle,iowait}_time for nohz") did not take into account that one some architectures jiffies and cputime use different units. This causes get_idle_time() to return numbers in the wrong units, making the idle time fields in /proc/stat wrong. Instead of converting the usec value returned by get_cpu_{idle,iowait}_time_us to units of jiffies, use the new function usecs_to_cputime64 to convert it to the correct unit of cputime64_t.
