2018-02-15crypto: engine - Permit to enqueue all async requestsGravatar Corentin LABBE 2-166/+203
The crypto engine could actually only enqueue hash and ablkcipher request. This patch permit it to enqueue any type of crypto_async_request.

2018-02-15crypto: user - Replace GFP_ATOMIC with GFP_KERNEL in crypto_reportGravatar Jia-Ju Bai 1-1/+1
After checking all possible call chains to crypto_report here, my tool finds that crypto_report is never called in atomic context. And crypto_report calls crypto_alg_match which calls down_read, thus it proves again that crypto_report can call functions which may sleep. Thus GFP_ATOMIC is not necessary, and it can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself.

Crypto framework requires export/import in async hash. If driver do not implement them, wrapper functions in framework will be used, and it will cause error during ahash alg registration (unless one disables crypto internal tests). To make change in framework and expose this requirement, I will remove wrappers from crypto/ahash.c , but this can broke code which depends on them. Add empty hash export and import, with the same behaviour as in framework and expose this directly in driver.

except, again, POLLFREE and POLL_BUSY_LOOP. With this, we finally get to the promised end result: - POLL{IN,OUT,...} are plain integers and *not* in __poll_t, so any stray instances of ->poll() still using those will be caught by sparse. - eventpoll.c and select.c warning-free wrt __poll_t - no more kernel-side definitions of POLL... - userland ones are visible through the entire kernel (and used pretty much only for mangle/demangle) - same behavior as after the first series (i.e. sparc et.al. epoll(2) working correctly).

2018-02-11vfs: do bulk POLL* -> EPOLL* replacementGravatar Linus Torvalds 297-913/+913
This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Basically, that's what you suggested wrt KPOLL..., except that we can use EPOLL... instead - they already are arch-independent (and equal to what is currently kernel-side POLL...).

2018-02-10kconfig: remove const qualifier from sym_expand_string_value()Gravatar Masahiro Yamada 3-4/+4
This function returns realloc'ed memory, so the returned pointer must be passed to free() when done. So, 'const' qualifier is odd. It is allowed to modify the expanded string. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
