About enigmail in EdgeBSD

[Pierre Pronchery <khorben@xxxxxxxxxxx>]

			Dear EdgeBSD users,

this is an informal bug report (and reminder) that the enigmail add-on 
to Mozilla Thunderbird is currently broken in EdgeBSD. This is also a 
reason I am currently unable to sign and encrypt e-mails conveniently, 
sadly.

I have isolated the root cause of the problem, and it is related to W^X 
support in the kernel (PaX MPROTECT). The Javascript JIT engine from 
Mozilla Thunderbird crashes when using the add-on. For some reason this 
happens even after using paxctl(8) on the relevant binaries I could find:
/usr/pkg/lib/thunderbird/thunderbird
/usr/pkg/lib/thunderbird/thunderbird-bin
/usr/pkg/lib/thunderbird/plugin-container
(as found in pkgsrc's -current)

On the other hand Mozilla Firefox' JIT engine uses a different memory 
allocator that seems to know about W^X for a few versions now, and I 
have no trouble there at the moment - even with PIE, ASLR, and W^X enabled.

Cheers & HTH,
