Follow-ups

--- Mike Frysinger 2008-04-03 21:40:19

i think this was just the execv bug in uClibc that is now fixed ... is this

still an issue ?

i ran on trunk:

while /execve05 -F /test3 ; do :; done

and it seemed to work OK

--- Bryan Wu 2008-04-07 03:11:07

In the trunk:

We tested trunk kernel compiled with trunk toolchain. It runs OK, but when I

try CTRL+C to stop the while loop here, it crashed:

execve05 1 PASS : call generated expected ETXTBSY error

execve05 1 PASS : call generated expected ETXTBSY error

I guess that some uclibc execve bug fixing did not be backported to toolchain

08R1 branch.

-Bryan Wu

--- Mike Frysinger 2008-04-07 04:03:55

all the uclibc exec changes should be in the branch (as well as the last

release)

you have the binary/symbols in question ... please decode them. i dont know

what all the offsets in "test3" are in your dump

--- Sonic Zhang 2009-01-07 05:34:47

The crash disappears on SVN head. Child process should be dealt with properly

for NOMMU. Fixed.

--- Vivi Li 2009-01-08 05:35:08
