Signed-off-by: Hugh Dickins <hugh@veritas.com> It seems eccentric to implement MAP_POPULATE only on PROT_NONE mappings: do_mmap_pgoff is passing down prot, then sys_remap_file_pages verifies it's not set. I guess that's an oversight from when we realized that the prot arg to sys_remap_file_pages was misdesigned. There's another oddity whose heritage is harder for me to understand, so please let me leave it to you: sys_remap_file_pages is declared as asmlinkage in mm/fremap.c, but is the one syscall declared without asmlinkage in include/linux/syscalls.h.

From: Jeff Mahoney <jeffm@suse.com> The following is a patch to fix a locking problem in ACL/xattr code. It manifests when a user attempts to set an xattr on a file which they do not own, and on which an ACL is applied. What happens is this: reiserfs_setxattr [write lock inode xattr sem] ->xattr_set -> lookup -> __reiserfs_permission [if conditions above are met, and need_lock= is unset, read lock inode xattr sem] *lockup* Since we already keep track of when to lock during permission calls, the fix is simple: just make the locking conditional as it was before.

From: Ben Fennema <bfennema@falcon.csc.calpoly.edu> The problem occured when files were stored on the disc in 16-bit per character mode when all the upper bits were 0. The fs module converted the file name given by the user to a 8-bit per character string to compare, so the comparison always failed. The patch maps the file from disc into the current locale and then compares it directly to the file name given by the user.

From: Michael Hunold <hunold@convergence.de> The attached patch changes my "Multimedia eXtension Board" (MXB) Video4Linux-driver to use the standard saa7111 video decoder infrastructure (to which I recently submitted changes through Ronald Bultje) instead of some home-brewn direct-access stuff. Nothing serious, but it removes code duplication and makes the code use the video decoder api.

From: <viro@parcelfarce.linux.theplanet.co.uk> init/initramfs.c::do_skip() has an off-by-one that leads to unpacking failures for some gzipped cpio images. We have static int __init do_skip(void) { if (this_header + count <= next_header) { eat(count); return 1; } else { eat(next_header - this_header); state = next_state; return 0; } } and that <= should actually be <. It almost never matters, since if we hit the boundary case (header ending exactly on the gunzip window end) the current variant will simply end up doing extra call of do_skip() when we get to the next window and that will finish the work (assign state). The only exception is when we hit that in the last window. That is, if there's nothing after the final header (trailer). Then we miss the final state transition (Skip -> Reset) and get "junk in archive" panic. Normally cpio(1) pads the image to multiple of 512, so we actually have a bunch of zeroes after the trailer. And that almost always saves our butts - trailer is followed by zeroes, so we get to Reset state just fine. So we never see that on small in-kernel image (it's less than 512 bytes, so it gets a lot of padding) and we almost never see that on external ones (1:127 odds of hitting the bug).

Signed-off-by: Petr Vandrovec <vandrove@vc.cvut.cz> Some people expressed interest in having possibility to set CRTC <-> outputs mapping at boot time, without having to use 'matroxset' later after kernel boots. This patch adds option 'video=matroxfb:outputs:XYZ', where X sets which CRTC will connect to primary output, Y sets secondary output and Z sets DVI output. In addition to that I also added missing memset() into maven, which was broken since i2c was kobjectified.

From: Olaf Kirch <okir@suse.de> I have been chasing a corruption of current->group_info on PPC during NFS stress tests. The problem seems to be that nfsd is messing with its group_info quite a bit, while some monitoring processes look at /proc/<pid>/status and do a get_group_info/put_group_info without any locking. This problem can be reproduced on ppc platforms within a few seconds if you generate some NFS load and do a "cat /proc/XXX/status" of an nfsd thread in a tight loop. I therefore think changes to current->group_info, and querying it from a different process, needs to be protected using the task_lock. (akpm: task->group_info here is safe against exit() because the task holds a ref on group_info which is released in __put_task_struct, and the /proc file has a ref on the task_struct).

ep_send_events() uses ~350 bytes of stack for a local buffer of events to send to userspace. The patch fixes that by removing the double-buffering altogether. A pipe-based microbenchmark from Davide Libenzi <davidel@xmailserver.org> was sped up by 1-2%.

From: Ingo Molnar <mingo@elte.hu> printk currently does if (oops_in_progres) bust_printk_locks(); which means that once we oops, the printk locking is 100% ineffective and multiple CPUs make an unreadable mess on a serial console. It's a significant development hassle. Fix that up by only popping locks once per ten seconds. akpm@osdl.org did: - Bump the timeout to 30 seconds - 9600 baud is slow. - Handle jiffy wraps: change the logic so that we only skip the lockbust if the current time is within 30 seconds of the previous lockbusting attempt.

From: "J. Bruce Fields" <bfields@fieldses.org> The kernel currently prints: nfsd: nobody listening for auth.unix.ip upcall; has some daemon not been started? on every bootup, during initscripts. Neil Brown <neilb@cse.unsw.edu.au> says: It was part of the recent set of idmapper patches. Bruce wanted the admin to get a warning when the idmapper daemon wasn't running. I thought the same warning should apply to any daemon that responded to upcalls. In the case of auth.unix.ip it isn't strictly necessary for a daemon to be running (for comparability with 2.4). You can get rid of the warning by doing: mount -t nfsd nfsd /proc/fs/nfs before mountd is started (init scripts should start doing this I hope, but distributions don't tend to use the init script from nfs-utils, so it is hard to push it). This will trigger mountd to listen on auth.unix.ip and others. That's a hassle, so Bruce's patch limits the warning purely to the new idmapper cache. It provides a callback in the cache_detail that individual caches can use to log messages when upcalls fail because a userspace daemon not running. Implement this method for the idmapping caches.
