2005-08-17[PATCH] nfsd to unlock kernel before exitingSteven Rostedt
The nfsd holds the big kernel lock upon exit, when it really shouldn't. Not to mention that this breaks Ingo's RT patch. This is a trivial fix to release the lock. Ingo, this patch also works with your kernel, and stops the problem with nfsd. Note, there's a "goto out;" where "out:" is right above svc_exit_thread. The point of the goto also holds the kernel_lock, so I don't see any problem here in releasing it.

2005-08-17[PATCH] NPTL signal delivery deadlock fixBhavesh P. Davda
This bug is quite subtle and only happens in a very interesting situation where a real-time threaded process is in the middle of a coredump when someone whacks it with a SIGKILL. However, this deadlock leaves the system pretty hosed and you have to reboot to recover. Not good for real-time priority-preemption applications like our telephony application, with 90+ real-time (SCHED_FIFO and SCHED_RR) processes, many of them multi-threaded, interacting with each other for high volume call processing.

2005-08-17[ARM] 2850/1: Remove duplicate UART I/O mapping from s3c2410_iodescDimitry Andric
Patch from Dimitry Andric This patch removes the initial UART I/O mapping from s3c2410_iodesc, since the same mapping is already done in the function s3c24xx_init_io in the file arch/arm/mach-s3c2410/cpu.c, through the s3c_iodesc array. I'm not sure if duplicate mappings do any harm, but it's simply redundant. Also, in s3c2440.c the UART I/O mapping is NOT done. Additionally, I put a comma behind the last mapping, to ease copy/pasting stuff around, and make the style consistent with s3c2440.c and other files.

2005-08-16[PATCH] iSeries build with newer assemblers and compilersStephen Rothwell
Paulus suggested that we put xLparMap in its own .c file so that we can generate a .s file to be included into head.S. This doesn't get around the problem of having it at a fixed address, but it makes it more palatable. It would be good if this could be included in 2.6.13 as it solves our build problems with various versions of binutils and gcc. In particular, it allows us to build an iSeries kernel on Debian unstable using their biarch compiler. This has been built and booted on iSeries and built for pSeries and g5.

2005-08-16[TCP]: Fix bug #5070: kernel BUG at net/ipv4/tcp_output.c:864Herbert Xu
1) We send out a normal sized packet with TSO on to start off. 2) ICMP is received indicating a smaller MTU. 3) We send the current sk_send_head which needs to be fragmented since it was created before the ICMP event. The first fragment is then sent out. At this point the remaining fragment is allocated by tcp_fragment. However, its size is padded to fit the L1 cache-line size therefore creating tail-room up to 124 bytes long. This fragment will also be sitting at sk_send_head. 4) tcp_sendmsg is called again and it stores data in the tail-room of of the fragment. 5) tcp_push_one is called by tcp_sendmsg which then calls tso_fragment since the packet as a whole exceeds the MTU. At this point we have a packet that has data in the head area being fed to tso_fragment which bombs out. My take on this is that we shouldn't ever call tcp_fragment on a TSO socket for a packet that is yet to be transmitted since this creates a packet on sk_send_head that cannot be extended. So here is a patch to change it so that tso_fragment is always used in this case. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-08-16[PATCH] NFS: Ensure we always update inode->i_mode when doing O_EXCL createsTrond Myklebust
When the client performs an exclusive create and opens the file for writing, a Netapp filer will first create the file using the mode 01777. It does this since an NFSv3/v4 exclusive create cannot immediately set the mode bits. The 01777 mode then gets put into the inode->i_mode. After the file creation is successful, we then do a setattr to change the mode to the correct value (as per the NFS spec). The problem is that nfs_refresh_inode() no longer updates inode->i_mode, so the latter retains the 01777 mode. A bit later, the VFS notices this, and calls remove_suid(). This of course now resets the file mode to inode->i_mode & 0777. Hey presto, the file mode on the server is now magically changed to 0777. Duh...

2005-08-15[PATCH] intelfb/fbdev: Save info->flags in a local variableAntonino A. Daplas
Reported by: Pavel Kysilka (Bugzilla Bug 5059) The intelfb driver does not keep resolution set with fbset after switching to anot console and back. Steps to reproduce: initial options: tty1,tty2 - 1024x768-60 1) tty1 - fbset after booting (1024x768-60) 2) tty1 - fbset 800x600-100 tty1: 800x600-100 3) swith to tty2, swith to tty1 tty1: 1024x768-60 (the same resolution as default from kernel booting) This bug is caused by intelfb unintentionally destroying info->flags in set_par(). Therefore the flag, FBINFO_MISC_USEREVENT used to notify fbcon of a mode change was cleared causing the above problem. This bug though is not intelfb specific, as other drivers may also be affected. The fix is to save info->flags in a local variable before calling any of the driver hooks. A more definitive fix (for post 2.6.13) is to separate info->flags into one that is set by the driver and another that is set by core fbdev/fbcon.
