2009-02-06eCryptfs: Regression in unencrypted filename symlinksTyler Hicks
The addition of filename encryption caused a regression in unencrypted filename symlink support. ecryptfs_copy_filename() is used when dealing with unencrypted filenames and it reported that the new, copied filename was a character longer than it should have been. This caused the return value of readlink() to count the NULL byte of the symlink target. Most applications don't care about the extra NULL byte, but a version control system (bzr) helped in discovering the bug.

2009-02-06x86-64: fix int $0x80 -ENOSYS returnRoland McGrath
One of my past fixes to this code introduced a different new bug. When using 32-bit "int $0x80" entry for a bogus syscall number, the return value is not correctly set to -ENOSYS. This only happens when neither syscall-audit nor syscall tracing is enabled (i.e., never seen if auditd ever started). Test program: /* gcc -o int80-badsys -m32 -g int80-badsys.c Run on x86-64 kernel. Note to reproduce the bug you need auditd never to have started. */ #include <errno.h> #include <stdio.h> int main (void) { long res; asm ("int $0x80" : "=a" (res) : "0" (99999)); printf ("bad syscall returns %ld\n", res); return res != -ENOSYS; } The fix makes the int $0x80 path match the sysenter and syscall paths.

2009-02-06elf core dump: fix get_user useRoland McGrath
The elf_core_dump() code does its work with set_fs(KERNEL_DS) in force, so vma_dump_size() needs to switch back with set_fs(USER_DS) to safely use get_user() for a normal user-space address. Checking for VM_READ optimizes out the case where get_user() would fail anyway. The vm_file check here was already superfluous given the control flow earlier in the function, so that is a cleanup/optimization unrelated to other changes but an obvious and trivial one.

2009-02-06vfs: Don't call attach_nobh_buffers() with an empty listDave Kleikamp
This is a modification of a patch by Bill Pemberton <wfp5p@virginia.edu> nobh_write_end() could call attach_nobh_buffers() with head == NULL. This would result in a trap when attach_nobh_buffers() attempted to access bh->b_this_page. This can be illustrated by running the writev01 testcase from LTP on jfs. This error was introduced by commit 5b41e74a "vfs: fix data leak in nobh_write_end()". That patch did not take into account that if PageMappedToDisk() is true upon entry to nobh_write_begin(), then no buffers will be allocated for the page. In that case, we won't have to worry about a failed write leaving unitialized data in the page. Of course, head != NULL implies !page_has_buffers(page), so no need to test both.

For audio devices that do not have proper audio descriptors (e.g., Edirol UA-20), we use hardcoded parameters from our quirks list. However, we must still read the maximum packet size from the standard endpoint descriptor; otherwise, we might use packets that are too big and therefore rejected by the USB core.

2009-02-06md: Ensure an md array never has too many devices.NeilBrown
Each different metadata format supported by md supports a different maximum number of devices. We really should be enforcing this maximum in the kernel, but we aren't quite doing that properly. We currently only enforce it at the 'hot_add' point, which is an older interface which is not used by current userspace. We need to also enforce it at 'add_new_disk' time for active arrays and at 'do_md_run' time when starting a new array. So move the test from 'hot_add' into 'bind_rdev_to_array' which is called from both 'hot_add' and 'add_new_disk, and add a new test in 'analyse_sbs' which is called from 'do_md_run'. This bug (or missing feature) has been around "forever" and so the patch is suitable for any -stable that is currently maintained. Cc: stable@kernel.org Signed-off-by: NeilBrown <neilb@suse.de>
2009-02-06md: Fix a bug in linear.c causing which_dev() to return the wrong device.Andre Noll
ab5bd5cbc8d4b868378d062eed3d4240930fbb86 introduced the following bug in linear software raid for large arrays on 32 bit machines: which_dev() computes the device holding a given sector by shifting down the sector number to a 32 bit range, dividing by the array spacing and looking up the resulting index in the hash table of the array. Because the computed index might be slightly too small, a loop at the end of which_dev() increases the index until the given sector actually falls into the range of the device associated with that index. The changes of the above mentioned commit caused this loop to check whether the _index_ rather than the sector number is small enough, effectively bypassing the loop and thus possibly returning the wrong device. As reported by Simon Kirby, this leads to errors such as linear_make_request: Sector 2340486136 out of bounds on dev sdi: 156301312 sectors, offset 2109870464 Fix this bug by introducing a local variable for the index so that the variable containing the passed sector is left unchanged.

2009-02-06md: Allow read error in a single drive raid1 to be passed up.NeilBrown
If a raid1 only has a single working device and gets a read error, we choose to simply return that error up to the filesystem (or whatever) rather than failing the whole array. However the codes doesn't quite do that. We attempt a readbalance which allocates the same drive, so we retry the read - indefinitely. Instead: If read_balance in the error case chooses the same drive that just failed, treat it as a failure and don't retry. Signed-off-by: NeilBrown <neilb@suse.de>
