Guys,
I need some help. I am trying to change the function tcp_accept_init()
inside src/io/bmi/bmi_tcp/bmi-tcp.c. This function has the accept() call (ie.
it is the first point of contact by the pvfs client to the server). At this
point I need to make some immediate checks and decide if I want to allow this
client any further access to the server. If I find out that I do NOT want to
allow access I need to cleanly return an error to the client. If I do a return
(-1) from this function, however, the server's bmi thread simply crashes giving
me the foll output:
====================================================================================
[E 11/15 17:24] src/io/bmi/bmi.c line 957: Error: critical BMI_testcontext
failure.
[E 11/15 17:24] [bt] pvfs2-server(BMI_testcontext+0x274) [0x807a344]

[E 11/15 17:24]
PVFS2 server got signal 2 (server_status_flag: 262143)
======================================================================================
I am using pvfs-2.6.3. At this point in the code, i see a comment which says:
======================================================================================
/* FIXME:
* BIG KLUDGE
* if we return an error, pvfs2-server's bmi thread simply terminates.
* hence I am returning 0 here. Need to ask Phil or RobR about this...
*/
=======================================================================================
Is there any fix for this problem yet?
