* git://git.infradead.org/hdrcleanup-2.6: (63 commits) [S390] __FD_foo definitions. Switch to __s32 types in joystick.h instead of C99 types for consistency. Add <sys/types.h> to headers included for userspace in <linux/input.h> Move inclusion of <linux/compat.h> out of user scope in asm-x86_64/mtrr.h Remove struct fddi_statistics from user view in <linux/if_fddi.h> Move user-visible parts of drivers/s390/crypto/z90crypt.h to include/asm-s390 Revert include/media changes: Mauro says those ioctls are only used in-kernel(!) Include <linux/types.h> and use __uXX types in <linux/cramfs_fs.h> Use __uXX types in <linux/i2o_dev.h>, include <linux/ioctl.h> too Remove private struct dx_hash_info from public view in <linux/ext3_fs.h> Include <linux/types.h> and use __uXX types in <linux/affs_hardblocks.h> Use __uXX types in <linux/divert.h> for struct divert_blk et al. Use __u32 for elf_addr_t in <asm-powerpc/elf.h>, not u32. It's user-visible. Remove PPP_FCS from user view in <linux/ppp_defs.h>, remove __P mess entirely Use __uXX types in user-visible structures in <linux/nbd.h> Don't use 'u32' in user-visible struct ip_conntrack_old_tuple. Use __uXX types for S390 DASD volume label definitions which are user-visible S390 BIODASDREADCMB ioctl should use __u64 not u64 type. Remove unneeded inclusion of <linux/time.h> from <linux/ufs_fs.h> Fix private integer types used in V4L2 ioctls. ... Manually resolve conflict in include/linux/mtd/physmap.h

2006-05-19[SCTP]: Respect the real chunk length when walking parameters.Vladislav Yasevich
When performing bound checks during the parameter processing, we want to use the real chunk and paramter lengths for bounds instead of the rounded ones. This prevents us from potentially walking of the end if the chunk length was miscalculated. We still use rounded lengths when advancing the pointer. This was found during a conformance test that changed the chunk length without modifying parameters.

2006-05-05[SCTP]: Allow spillover of receive buffer to avoid deadlock.Neil Horman
This patch fixes a deadlock situation in the receive path by allowing temporary spillover of the receive buffer. - If the chunk we receive has a tsn that immediately follows the ctsn, accept it even if we run out of receive buffer space and renege data with higher TSNs. - Once we accept one chunk in a packet, accept all the remaining chunks even if we run out of receive buffer space.

2006-02-02[SCTP]: Fix 'fast retransmit' to send a TSN only once.Vlad Yasevich
SCTP used to "fast retransmit" a TSN every time we hit the number of missing reports for the TSN. However the Implementers Guide specifies that we should only "fast retransmit" a given TSN once. Subsequent retransmits should be timeouts only. Also change the number of missing reports to 3 as per the latest IG(similar to TCP).

2006-01-17[SCTP]: Fix couple of races between sctp_peeloff() and sctp_rcv().Sridhar Samudrala
Validate and update the sk in sctp_rcv() to avoid the race where an assoc/ep could move to a different socket after we get the sk, but before the skb is added to the backlog. Also migrate the skb's in backlog queue to new sk when doing a peeloff. Signed-off-by: Sridhar Samudrala <sri@us.ibm.com>
2006-01-17[SCTP]: Fix machine check/connection hang on IA64.Vlad Yasevich
sctp_unpack_cookie used an on-stack array called digest as a result/out parameter in the call to crypto_hmac. However, hmac code (crypto_hmac_final) assumes that the 'out' argument is in virtual memory (identity mapped region) and can use virt_to_page call on it. This does not work with the on-stack declared digest. The problems observed so far have been: a) incorrect hmac digest b) machine check and hardware reset. Solution is to define the digest in an identity mapped region by kmalloc'ing it. We can do this once as part of the endpoint structure and re-use it when verifying the SCTP cookie.

2006-01-17[SCTP]: Fix bad sysctl formatting of SCTP timeout values on 64-bit m/cs.Vlad Yasevich

2006-01-17[SCTP]: Fix sctp_cookie alignment in the packet.Vlad Yasevich
On 64 bit architectures, sctp_cookie sent as part of INIT-ACK is not aligned on a 64 bit boundry and thus causes unaligned access exceptions. The layout of the cookie prameter is this: |<----- Parameter Header --------------------|<--- Cookie DATA -------- ----------------------------------------------------------------------- | param type (16 bits) | param len (16 bits) | sig [32 bytes] | cookie.. ----------------------------------------------------------------------- The cookie data portion contains 64 bit values on 64 bit architechtures (timeval) that fall on a 32 bit alignment boundry when used as part of the on-wire format, but align correctly when used in internal structures. This patch explicitely pads the on-wire format so that it is properly aligned. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: Sridhar Samudrala <sri@us.ibm.com>

2005-11-11[SCTP]: Fix ia64 NaT consumption fault with sctp_sideffect commands.Vladislav Yasevich
On ia64, it is possible to get NaT Consumption Fault and a kernel panic when initializing sctp sideeffect commands arguments. The union sctp_arg_t contains different sized elements and when loading a smaller sized element (32 or 16 bits), it is possible for a speculative load to fail and result in a NaT bit set which causes a kernel crash. The easy way to get around it is to load the largerst member of the union.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
