c7509de7cc [msan] Fix syscall handlers for pipe, pipe2, socketpair. 
These syscalls write two file descriptors into the output buffer, not one.

ecfcc07a48 [msan] Don't check dstaddr in sendto() interceptor. 
Dstaddr may contain uninitialized padding at the end (common
implementations accept larger addrlen and ignore the extra bytes).
Also, depending on the socket state, dstaddr argument may be ignored.

1a1973b846 [msan] Fix process_vm_readv test. 
The check for the glibc version was not working as expected (dlsym
was finding the interceptor instead of the libc implementation).

1e9aadba17 [msan] Re-submit test for process_vm_readv. 
Includes a workaround for glibc < 2.15, which does not provide the
function under test.

7b04acd28d [msan] Temporarily remove a failing test to fix the bot.
