#58 Bug in hash.c

[Anonymous]

hey,
there is a Bug in in function
find_entry and find_in_hash_update

You need also to enter the Critical-Section like this:

qtime_csenter();
for(e = h[k]; e && e->dst != esrc; e = e->next)
qtime_csexit();

I have running a vde_switch with this patch since 137 days. The Network has 39 VLANs with 2000 nodes (round).

Thank you Volker for your report.

I am considering to solve the problem in a different way: using ppoll insted of poll for vde_switch's main loop.

qtime_csenter/csexit require a system call each, so your patch could slow down the packet dispatching.

I would like to have more info on the race conditions you have had.
thank you... renzo davoli/rd235
