Subject: [PATCH] linux-user: fix statfs
|
|
|
|
The statfs syscall should always memset(0) its full struct extent before
|
|
writing to it. Newer versions of the syscall use one of the reserved fields
|
|
for flags, which would otherwise get stale values from uncleaned memory.
|
|
|
|
This fixes libarchive for me, which got confused about the return value of
|
|
pathconf("/", _PC_REC_XFER_ALIGN) otherwise, as it some times gave old pointers
|
|
as return value.
