| | | | | | | | | | | | | | | | | (i.e., the return value would overflow), set errno to EOVERFLOW and return an error. This improves the chances that buggy applications -- for instance, ones that pass in a negative integer as the size due to a bogus calculation -- will fail in safe ways. Returning an error in these situations is specified by POSIX, but POSIX appears to have an off-by-one error that isn't duplicated in this change. Previously, some of these functions would silently cap the size at INT_MAX+1, and others would exit with an error after writing more than INT_MAX characters. PR: 39256 MFC after: 2 weeks

| | | | | | | | | | | | | | | | | | | | | | | | | | | way: first they are compiled to assembly, then some sed'ing is done on the assembly, and lastly the assembly is compiled to an object file. This last step is done using ${CC}, and not ${AS}, because when the compiler is clang, it outputs directives that are too advanced for our old gas. So we use clang's integrated assembler instead. (When the compiler is gcc, it just calls gas, and nothing is different, except one extra fork.) However, in the .s to .o rules in lib/csu/$ARCH/Makefile, I still passed CFLAGS to the compiler, instead of ACFLAGS, which are specifically for compiling .s files. In case you are using '-g' for debug info anywhere in your CFLAGS, it causes the .s files to already contain debug information in the assembly itself. In the next step, the .s files are also compiled using '-g', and if the compiler is clang, it complains: "error: input can't have .file dwarf directives when -g is used to generate dwarf debug info for assembly code". Fix this by using ${ACFLAGS} for compiling the .s files instead. Reported by: jasone MFC after: 1 week

It's very difficult to fix the identifiers used by devstat, so this change is simply being backed out. Since changes to 3rd-party code seem likely, and may be necessary to properly fix 32-bit binaries on 64-bit kernel, it would seem better to make more invasive changes to fix GEOM's problems with 32-bit compatibility in general. The right thing to do is to replace all of the use of pointers as opaque identifiers with a fixed-size (64-bit or even 32-bit should be enough for tracking unique GEOM elments) field. That probably maintains source compatibility with most GEOM consumers, and allows xml2tree to make better assumptions about how to decode the identifiers. Submitted by: Anton Yuzhaninov

The new operation UMTX_OP_MUTEX_WAKE2 try to fix the problem. It requires thread library to clear the lock word entirely, then call the WAKE2 operation to check if there is any waiter in kernel, and try to wake up a thread, if necessary, the contention bit is set again by the operation. This also mitgates the chance that other threads find the contention bit and try to enter kernel to compete with each other to wake up sleeping thread, this is unnecessary. With this change, the mutex owner is no longer holding the mutex until it reaches a point where kernel umtx queue is locked, it releases the mutex as soon as possible. Performance is improved when the mutex is contensted heavily. On Intel i3-2310M, the runtime of a benchmark program is reduced from 26.87 seconds to 2.39 seconds, it even is better than UMTX_OP_MUTEX_WAKE which is deprecated now. http://people.freebsd.org/~davidxu/bench/mutex_perf.c
