FS#766 - Intermittent SIGSEGV crash of dnsmasq-full
User who did this - Christian Kujau (ckujau)
For the record, this is still an issue with 17.01.2 and Dnsmasq version 2.77:
kernel: [ 2860.890789]
kernel: [ 2860.890789] do_page_fault(): sending SIGSEGV to dnsmasq for invalid write access to 00552000
kernel: [ 2860.899402] epc = 77cd488c in libc.so[77c62000+92000]
kernel: [ 2860.904552] ra = 00406c41 in dnsmasq[400000+21000]
kernel: [ 2860.909537]
I came across this one while playing around with //dnseval// from the [[https://github.com/farrokhi/dnsdiag|dnsdiag]] package. Simply calling //dnseval foo// was enough to make //dnsmasq// crash :-|
But, as this crashes the lastest git checkout from //dnsmasq// too, I shall report this upstream, of course. have reported this to the [[http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2017q3/011692.html|dnsmasq-discuss]] mailing list.
If somebody wants to take a stab at the MIPS core dump (attached), please do, as I don't have a LEDE build environment set up yet.
One or more files have been attached.
