2006-03-25[PATCH] POLLRDHUP/EPOLLRDHUP handling for half-closed devices notificationsDavide Libenzi
Implement the half-closed devices notifiation, by adding a new POLLRDHUP (and its alias EPOLLRDHUP) bit to the existing poll/select sets. Since the existing POLLHUP handling, that does not report correctly half-closed devices, was feared to be changed, this implementation leaves the current POLLHUP reporting unchanged and simply add a new bit that is set in the few places where it makes sense. The same thing was discussed and conceptually agreed quite some time ago: http://lkml.org/lkml/2003/7/12/116 Since this new event bit is added to the existing Linux poll infrastruture, even the existing poll/select system calls will be able to use it. As far as the existing POLLHUP handling, the patch leaves it as is. The pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing archs and sets the bit in the six relevant files. The other attached diff is the simple change required to sys/epoll.h to add the EPOLLRDHUP definition. There is "a stupid program" to test POLLRDHUP delivery here: http://www.xmailserver.org/pollrdhup-test.c It tests poll(2), but since the delivery is same epoll(2) will work equally.

2006-03-24[PATCH] cpuset memory spread: slab cache filesystemsPaul Jackson
Mark file system inode and similar slab caches subject to SLAB_MEM_SPREAD memory spreading. If a slab cache is marked SLAB_MEM_SPREAD, then anytime that a task that's in a cpuset with the 'memory_spread_slab' option enabled goes to allocate from such a slab cache, the allocations are spread evenly over all the memory nodes (task->mems_allowed) allowed to that task, instead of favoring allocation on the node local to the current cpu. The following inode and similar caches are marked SLAB_MEM_SPREAD: file cache ==== ===== fs/adfs/super.c adfs_inode_cache fs/affs/super.c affs_inode_cache fs/befs/linuxvfs.c befs_inode_cache fs/bfs/inode.c bfs_inode_cache fs/block_dev.c bdev_cache fs/cifs/cifsfs.c cifs_inode_cache fs/coda/inode.c coda_inode_cache fs/dquot.c dquot fs/efs/super.c efs_inode_cache fs/ext2/super.c ext2_inode_cache fs/ext2/xattr.c (fs/mbcache.c) ext2_xattr fs/ext3/super.c ext3_inode_cache fs/ext3/xattr.c (fs/mbcache.c) ext3_xattr fs/fat/cache.c fat_cache fs/fat/inode.c fat_inode_cache fs/freevxfs/vxfs_super.c vxfs_inode fs/hpfs/super.c hpfs_inode_cache fs/isofs/inode.c isofs_inode_cache fs/jffs/inode-v23.c jffs_fm fs/jffs2/super.c jffs2_i fs/jfs/super.c jfs_ip fs/minix/inode.c minix_inode_cache fs/ncpfs/inode.c ncp_inode_cache fs/nfs/direct.c nfs_direct_cache fs/nfs/inode.c nfs_inode_cache fs/ntfs/super.c ntfs_big_inode_cache_name fs/ntfs/super.c ntfs_inode_cache fs/ocfs2/dlm/dlmfs.c dlmfs_inode_cache fs/ocfs2/super.c ocfs2_inode_cache fs/proc/inode.c proc_inode_cache fs/qnx4/inode.c qnx4_inode_cache fs/reiserfs/super.c reiser_inode_cache fs/romfs/inode.c romfs_inode_cache fs/smbfs/inode.c smb_inode_cache fs/sysv/inode.c sysv_inode_cache fs/udf/super.c udf_inode_cache fs/ufs/super.c ufs_inode_cache net/socket.c sock_inode_cache net/sunrpc/rpc_pipe.c rpc_inode_cache The choice of which slab caches to so mark was quite simple. I marked those already marked SLAB_RECLAIM_ACCOUNT, except for fs/xfs, dentry_cache, inode_cache, and buffer_head, which were marked in a previous patch. Even though SLAB_RECLAIM_ACCOUNT is for a different purpose, it marks the same potentially large file system i/o related slab caches as we need for memory spreading. Given that the rule now becomes "wherever you would have used a SLAB_RECLAIM_ACCOUNT slab cache flag before (usually the inode cache), use the SLAB_MEM_SPREAD flag too", this should be easy enough to maintain. Future file system writers will just copy one of the existing file system slab cache setups and tend to get it right without thinking.

2006-03-23[PATCH] WE-20 for kernel 2.6.16Jean Tourrilhes
This is version 20 of the Wireless Extensions. This is the completion of the RtNetlink work I started early 2004, it enables the full Wireless Extension API over RtNetlink. Few comments on the patch : o totally driver transparent, no change in drivers needed. o iwevent were already RtNetlink based since they were created (around 2.5.7). This adds all the regular SET and GET requests over RtNetlink, using the exact same mechanism and data format as iwevents. o This is a Kconfig option, as currently most people have no need for it. Surprisingly, patch is actually small and well encapsulated. o Tested on SMP, attention as been paid to make it 64 bits clean. o Code do probably too many checks and could be further optimised, but better safe than sorry. o RtNetlink based version of the Wireless Tools available on my web page for people inclined to try out this stuff. I would also like to thank Alexey Kuznetsov for his helpful suggestions to make this patch better. Signed-off-by: Jean Tourrilhes <jt@hpl.hp.com> Signed-off-by: John W.

2006-03-22[TCP]: Do not use inet->id of global tcp_socket when sending RST.Alexey Kuznetsov
The problem is in ip_push_pending_frames(), which uses: if (!df) { __ip_select_ident(iph, &rt->u.dst, 0); } else { iph->id = htons(inet->id++); } instead of ip_select_ident(). Right now I think the code is a nonsense. Most likely, I copied it from old ip_build_xmit(), where it was really special, we had to decide whether to generate unique ID when generating the first (well, the last) fragment. In ip_push_pending_frames() it does not make sense, it should use plain ip_select_ident() instead. Signed-off-by: Alexey Kuznetsov <kuznet@ms2.inr.ac.ru> Signed-off-by: David S.

2006-03-22[NETFILTER]: ctnetlink: Fix expectaction mask dumpingPablo Neira Ayuso
The expectation mask has some particularities that requires a different handling. The protocol number fields can be set to non-valid protocols, ie. l3num is set to 0xFFFF. Since that protocol does not exist, the mask tuple will not be dumped. Moreover, this results in a kernel panic when nf_conntrack accesses the array of protocol handlers, that is PF_MAX (0x1F) long. This patch introduces the function ctnetlink_exp_dump_mask, that correctly dumps the expectation mask. Such function uses the l3num value from the expectation tuple that is a valid layer 3 protocol number. The value of the l3num mask isn't dumped since it is meaningless from the userspace side.
