[NETLINK]: Fix a severe bug

2006-02-10T00:43:38+00:00

netlink overrun was broken while improvement of netlink.
Destination socket is used in the place where it was meant to be source socket,
so that now overrun is never sent to user netlink sockets, when it should be,
and it even can be set on kernel socket, which results in complete deadlock
of rtnetlink.

Suggested fix is to restore status quo passing source socket as additional
argument to netlink_attachskb().

A little explanation: overrun is set on a socket, when it failed
to receive some message and sender of this messages does not or even
have no way to handle this error. This happens in two cases:
1. when kernel sends something. Kernel never retransmits and cannot
   wait for buffer space.
2. when user sends a broadcast and the message was not delivered
   to some recipients.

[PATCH] Fix double decrement of mqueue_mnt->mnt_count in sys_mq_open

2006-01-14T20:38:17+00:00

Fixed the refcounting on failure exits in sys_mq_open() and
cleaned the logics up.  Rules are actually pretty simple - dentry_open()
expects vfsmount and dentry to be pinned down and it either transfers
them into created struct file or drops them.  Old code had been very
confused in that area - if dentry_open() had failed either in do_open()
or do_create(), we ended up dentry and mqueue_mnt dropped twice, once
by dentry_open() cleanup and then by sys_mq_open().

Fix consists of making the rules for do_create() and do_open()
same as for dentry_open() and updating the sys_mq_open() accordingly;
that actually leads to more straightforward code and less work on
normal path.

[PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_sem

2006-01-09T23:59:24+00:00

This patch converts the inode semaphore to a mutex. I have tested it on
XFS and compiled as much as one can consider on an ia64. Anyway your
luck with it might be different.

[PATCH] Make POSIX message queue sys_mq_open() honor umask

2005-09-27T20:30:45+00:00

We ignored umask when creating new queues via mq_open (when creating
with open() on mqueue fs it is ok of course).  According to the
specification this a bug.  This trivial patch fixes this.
