SubjectRE: bug with pipes with newest kernels (2.2.2)?
Date


The calling process:

pern:~% strace -p 523
read(4, 0x80a72f8, 0) = -1 EAGAIN (Resource
temporarily unavailable)
nanosleep(0xbffff67c, 0xbffff67c, 0x401146cc, 0x80972f8, 0x4) = 0
read(4, 0x80a72f8, 0) = -1 EAGAIN (Resource
temporarily unavailable)
nanosleep(0xbffff67c, 0xbffff67c, 0x401146cc, 0x80972f8, 0x4) = 0
read(4, 0x80a72f8, 0) = -1 EAGAIN (Resource
temporarily unavailable)
... and repeating


Here's what I get from the caller: (2.2.2, glibc-2.1.109)

ipc_subcall(0, 0xbffff72c, 0xbffff6ac, 0x8) = 0
recvfrom(3221222936, "", 1074877748, 0x80cf628, {...}, [3221223384]) = 0
read(3, 0x80df628, 0) = -1 EAGAIN (Try again)
ipc_subcall(0, 0xbffff72c, 0xbffff6ac, 0x8) = 0
recvfrom(3221222936, "", 1074877748, 0x80cf628, {...}, [3221223384]) = 0
read(3, 0x80df628, 0) = -1 EAGAIN (Try again)
ipc_subcall(0, 0xbffff72c, 0xbffff6ac, 0x8) = 0
recvfrom(3221222936, "", 1074877748, 0x80cf628, {...}, [3221223384]) = 0
read(3, 0x80df628, 0) = -1 EAGAIN (Try again)
ipc_subcall(0, 0xbffff72c, 0xbffff6ac, 0x8) = 0
recvfrom(3221222936, "", 1074877748, 0x80cf628, {...}, [3221223384]) = 0
read(3, 0x80df628, 0) = -1 EAGAIN (Try again)
ipc_subcall(0, 0xbffff72c, 0xbffff6ac, 0x8) = 0
recvfrom(3221222936, "", 1074877748, 0x80cf628, {...}, [3221223384]) = 0
read(3, 0x80df628, 0) = -1 EAGAIN (Try again)
ipc_subcall(0, 0xbffff72c, 0xbffff6ac, 0x8) = 0
