| | | | | | | | | | | We should use XDR_LEN to calculate reserved space in case the oid is not a multiple of 4. RESERVE_SPACE actually rounds up for us, but it's probably better to be careful here.

* nfsd: revoking of suid/sgid bits after chown() in a consistent wayStanislav Kholmanskikh2013-12-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is an inconsistency in the handling of SUID/SGID file bits after chown() between NFS and other local file systems. Local file systems (for example, ext3, ext4, xfs, btrfs) revoke SUID/SGID bits after chown() on a regular file even if the owner/group of the file has not been changed: ~# touch file; chmod ug+s file; chmod u+x file ~# ls -l file -rwsr-Sr-- 1 root root 0 Dec 6 04:49 file ~# chown root file; ls -l file -rwxr-Sr-- 1 root root 0 Dec 6 04:49 file but NFS doesn't do that: ~# touch file; chmod ug+s file; chmod u+x file ~# ls -l file -rwsr-Sr-- 1 root root 0 Dec 6 04:49 file ~# chown root file; ls -l file -rwsr-Sr-- 1 root root 0 Dec 6 04:49 file NFS does that only if the owner/group has been changed: ~# touch file; chmod ug+s file; chmod u+x file ~# ls -l file -rwsr-Sr-- 1 root root 0 Dec 6 05:02 file ~# chown bin file; ls -l file -rwxr-Sr-- 1 bin root 0 Dec 6 05:02 file See: http://pubs.opengroup.org/onlinepubs/9699919799/functions/chown.html "If the specified file is a regular file, one or more of the S_IXUSR, S_IXGRP, or S_IXOTH bits of the file mode are set, and the process has appropriate privileges, it is implementation-defined whether the set-user-ID and set-group-ID bits are altered." So both variants are acceptable by POSIX. This patch makes NFS to behave like local file systems. Signed-off-by: Stanislav Kholmanskikh <stanislav.kholmanskikh@oracle.com> Signed-off-by: J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux NFS server replies among other things to a "Check access permission" the following: NFS: File type = 2 (Directory) NFS: Mode = 040755 A netapp server replies here: NFS: File type = 2 (Directory) NFS: Mode = 0755 The RFC 1813 i read: fattr3 struct fattr3 { ftype3 type; mode3 mode; uint32 nlink; ... For the mode bits only the lowest 9 are defined in the RFC As far as I can tell, knfsd has always done this, so apparently it's harmless. Nevertheless, it appears to be wrong.

* nfsd: when reusing an existing repcache entry, unhash it firstJeff Layton2013-12-111-1/+8
| | | | | | | | | | | | | | | | | | | | | | | The DRC code will attempt to reuse an existing, expired cache entry in preference to allocating a new one. It'll then search the cache, and if it gets a hit it'll then free the cache entry that it was going to reuse. The cache code doesn't unhash the entry that it's going to reuse however, so it's possible for it end up designating an entry for reuse and then subsequently freeing the same entry after it finds it. This leads it to a later use-after-free situation and usually some list corruption warnings or an oops. Fix this by simply unhashing the entry that we intend to reuse. That will mean that it's not findable via a search and should prevent this situation from occurring.

This was prevalent when FTRACE_SELFTEST was enabled which enables all events several times, and caused the system bootup to pause for over a minute. This was tracked down to an addition of a synchronize_sched() performed when system call tracepoints are unregistered. The synchronize_sched() is needed between the unregistering of the system call tracepoint and a deletion of a tracing instance buffer. But placing the synchronize_sched() in the unreg of *every* system call tracepoint is a bit overboard. A single synchronize_sched() before the deletion of the instance is sufficient" * tag 'trace-fixes-3.13-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Only run synchronize_sched() at instance deletion time
| * tracing: Only run synchronize_sched() at instance deletion timeSteven Rostedt2013-12-052-10/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been reported that boot up with FTRACE_SELFTEST enabled can take a very long time. There can be stalls of over a minute. This was tracked down to the synchronize_sched() called when a system call event is disabled. As the self tests enable and disable thousands of events, this makes the synchronize_sched() get called thousands of times. The synchornize_sched() was added with d562aff93bfb53 "tracing: Add support for SOFT_DISABLE to syscall events" which caused this regression (added in 3.13-rc1). The synchronize_sched() is to protect against the events being accessed when a tracer instance is being deleted. When an instance is being deleted all the events associated to it are unregistered. The synchronize_sched() makes sure that no more users are running when it finishes. Instead of calling synchronize_sched() for all syscall events, we only need to call it once, after the events are unregistered and before the instance is deleted. The event_mutex is held during this action to prevent new users from enabling events.

See pci_driver. in local_pci_probe(). If you're wondering how this ever could have worked, it's because it used to be the case that only return values less than zero were interpreted as failure. But even in the current kernel if the driver registers its various entry points with the kernel, and then returns a value which is interpreted as failure, those registrations aren't undone, so the driver still mostly works. However, the driver's remove function wouldn't be called on rmmod, and pci power management functions wouldn't work. In the case of Smart Array, since it has a battery backed cache (or else no cache) even if the driver is not shut down properly as long as there is no outstanding i/o, nothing too bad happens, which is why it took so long to notice. Requesting backport to stable because the change to pci-driver.c which requires driver probe functions to return 0 occurred between 2.6.35 and 2.6.36 (the pci power management breakage) and again between 3.7 and 3.8 (pci_dev->driver getting set to NULL in local_pci_probe() preventing driver remove function from being called on rmmod.)

In some cases the physical device characteristics are reported even when the host adapter is processing commands on the device's behalf. This can lead to adapter firmware hangs or excessive I/O errors. This patch disables WRITE SAME for devices connected to host adapters that provide an emulated target. Driver writers can disable WRITE SAME by setting the no_write_same flag in the host adapter template. [jejb: fix up rejections due to eh_deadline patch] Signed-off-by: Martin K.

Since 'ima_field_data' contains dynamically allocated data (which length varies depending on the data associated to a selected template field), it is not enough to just free the memory reserved for a 'ima_template_entry' structure if something goes wrong. This patch creates the new function ima_free_template_entry() which walks the array of 'ima_field_data' structures, frees the memory referenced by the 'data' pointer and finally the space reserved for the 'ima_template_entry' structure. Further, it replaces existing kfree() that have a pointer to an 'ima_template_entry' structure as argument with calls to the new function.
