2008-03-08[CRYPTO] skcipher: Fix section mismatchesHerbert Xu
The previous patch to move chainiv and eseqiv into blkcipher created a section mismatch for the chainiv exit function which was also called from __init. This patch removes the __exit marking on it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-03-06[CRYPTO] xcbc: Fix crash with IPsecJoy Latten
When using aes-xcbc-mac for authentication in IPsec, the kernel crashes. It seems this algorithm doesn't account for the space IPsec may make in scatterlist for authtag. Thus when crypto_xcbc_digest_update2() gets called, nbytes may be less than sg[i].length. Since nbytes is an unsigned number, it wraps at the end of the loop allowing us to go back into loop and causing crash in memcpy. I used update function in digest.c to model this fix. Please let me know if it looks ok. Signed-off-by: Joy Latten <latten@austin.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-03-06[CRYPTO] xts: Use proper alignmentSebastian Siewior
The XTS blockmode uses a copy of the IV which is saved on the stack and may or may not be properly aligned. If it is not, it will break hardware cipher like the geode or padlock. This patch encrypts the IV in place so we don't have to worry about alignment.

2008-02-23[CRYPTO] skcipher: Move chainiv/seqiv into crypto_blkcipher moduleHerbert Xu
For compatibility with dm-crypt initramfs setups it is useful to merge chainiv/seqiv into the crypto_blkcipher module. Since they're required by most algorithms anyway this is an acceptable trade-off. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2008-02-14dentries: Extract common code to remove dentry from lruChristoph Lameter
Extract the common code to remove a dentry from the lru into a new function dentry_lru_remove(). Two call sites used list_del() instead of list_del_init(). AFAIK the performance of both is the same. dentry_lru_remove() does a list_del_init(). As a result dentry->d_lru is now always empty when a dentry is freed.

This is the central patch of a cleanup series. In most cases there is no good reason why someone would want to use a dentry for itself. This series reflects that fact and embeds a struct path into nameidata. Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on <dentry,vfsmount> pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

2008-02-14FLAT binaries: drop BINFMT_FLAT bad header magic warningMike Frysinger
The warning issued by fs/binfmt_flat.c when the format handler is given a non-FLAT and non-script executable is annoying to say the least when working with FDPIC ELF objects. If you build a kernel that supports both FLAT and FDPIC ELFs on no-mmu, every time you execute an FDPIC ELF, the kernel spits out this message. While I understand a lot of newcomers to the no-mmu world screw up generation of FLAT binaries, this warning is not usable for systems that support more than just FLAT.

2008-02-14cris: import memset.c from newlib: fixes compile error with newer (pre4.3) gccJesper Nilsson
Adrian Bunk reported the following compile error with a SVN head GCC: ... CC arch/cris/arch-v10/lib/memset.o /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/memset.c: In function 'memset': /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/memset.c:164: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/memset.c:165: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/memset.c:166: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/memset.c:167: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/memset.c:185: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/memset.c:189: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/memset.c:192: error: lvalue required as increment operand ... etc ... This is due to the use of the construct: *((long*)dst)++ = lc; Which is no longer legal since casts don't return an lvalue. The solution is to import the implementation from newlib, which is continually autotested together with GCC mainline, and uses the construct: *(long *) dst = lc; dst += 4; With this change, the generated code actually shrinks 76 bytes since gcc notices that it can use autoincrement for the move instruction in CRIS. text data bss dec hex filename 304 0 0 304 130 memset.old.o text data bss dec hex filename 228 0 0 228 e4 memset.o Since this is an import of a file from newlib, I'm not touching the formatting or correcting any checkpatch errors. Note also that even if the two files for the CRIS v10 and CRIS v32 are identical at the moment, it might be possible to tweak the CRIS v32 version. Thus, I'm not yet folding them into the same file, at least not until we've done some research on it.
