2009-11-18Add an intptr type to runtime; needed in FreeBSDDevon H. O'Dell2-1/+3
In thread.c, we need to cast to whatever the native size of intptr is on the system, but we only have uintptr available. They're the same size, but can't do signed casts without this one :). R=rsc CC=golang-dev http://codereview.appspot.com/156073 Committer: Russ Cox <rsc@golang.org>
2009-11-17FreeBSD/i386 workDevon H. O'Dell8-22/+492

2009-11-17runtime: do not create new threads during malloc.Russ Cox1-2/+5
the signal handling stack is a different size than the normal stack, so it cannot be allocated using the backup stack allocator. Fixes issue 250. R=agl1 CC=golang-dev http://codereview.appspot.com/157044
2009-11-17improve documentation of runtime. there was no mention of types.Rob Pike1-1/+3

2009-11-17FreeBSD-specific porting work.Devon H. O'Dell11-3/+690
cgo/libmach remain unimplemented. However, compilers, runtime, and packages are 100%. I still need to go through and implement missing syscalls (at least make sure they're all listed), but for all shipped functionality, this is done. Ship! ;) R=rsc, VenkateshSrinivas http://codereview.appspot.com/152142 Committer: Russ Cox <rsc@golang.org>

2009-11-13runtime: warn about SELinux based mmap failures on Linux.Adam Langley5-5/+32
SELinux will cause mmap to fail when we request w+x memory unless the user has configured their policies. We have a warning in make.bash, but it's quite likely that the policy will be reset at some point and then all their binaries start failing. This patch prints a warning on Linux when mmap fails with EACCES. R=rsc CC=golang-dev http://codereview.appspot.com/152086

2009-10-28Fix bug when sending via select.Adam Langley1-32/+19
selfree maintains a cache of Select structures for several sizes. In newselect, we'll use an entry from the cache if one is found. However, the Scase structures corresponding to a send may have been allocated for the wrong size. In this case we'll write off the end of the Scase into random memory and, generally, read some amount of junk in the receive. This patch fixes the issue by removing the cache, on the advice of rsc. R=rsc CC=go-dev http://go/go-review/1016002
2009-10-28mysterious bug: runtime.acid wasn't getting rebuiltRuss Cox2-5/+5

call. This uses the header files from a 32-bit Ubuntu Hardy system. The use of _LOOSE_KERNEL_NAMES seems right. The -D__ARCH_SI_UID_T works around a bug which appears to be fixed in later Linux versions. R=rsc http://go/go-review/1013015

2009-10-12stack overflow debugging and fix.Russ Cox6-24/+33
* in 6l, -K already meant check for stack underflow. add -KK to mean double-check stack overflows even in nosplit functions. * comment out print locks; they deadlock too easily but are still useful to put back for special occasions. * let runcgo assembly switch to scheduler stack without involving scheduler directly. because runcgo gets called from matchmg, it is too hard to keep it from being called on other stacks.
