This flags is added in the http channel interface by which developers can control the TLS
connections from JavaScript code (e.g. Add-ons). Basically, all the changes accounted for
plumbing this TLS flags from JavaScript level to C++ code responsible for calling NSS
module. We also added a unit test to make sure that separate connections are created if we
use different tlsFlags. Basically we used a concrete set of flag values that covers the
edge cases and check the hashkey generated in the connection info.
It's silly to use prmem.h within Firefox code given that in our configuration
its functions are just wrappers for malloc() et al. (Indeed, in some places we
mix PR_Malloc() with free(), or malloc() with PR_Free().)
This patch removes all uses, except for the places where we need to use
PR_Free() to free something allocated by another NSPR function; in those cases
I've added a comment explaining which function did the allocation.
This is straightforward mapping of PR_LOG levels to their LogLevel
counterparts:
PR_LOG_ERROR -> LogLevel::Error
PR_LOG_WARNING -> LogLevel::Warning
PR_LOG_WARN -> LogLevel::Warning
PR_LOG_INFO -> LogLevel::Info
PR_LOG_DEBUG -> LogLevel::Debug
PR_LOG_NOTICE -> LogLevel::Debug
PR_LOG_VERBOSE -> LogLevel::Verbose
Instances of PRLogModuleLevel were mapped to a fully qualified
mozilla::LogLevel, instances of PR_LOG levels in #defines were mapped to a
fully qualified mozilla::LogLevel::* level, and all other instances were
mapped to us a shorter format of LogLevel::*.
Bustage for usage of the non-fully qualified LogLevel were fixed by adding
|using mozilla::LogLevel;| where appropriate.

This also adds static checks that buffer overflows do not sneak in again in
the future.
Interestingly, this also makes (at least) GCC generate more efficient code.
For example, before, writing to the buffer in WriteV5AuthRequest would look
like this:
mov 0x38(%rbx),%eax
mov 0x28(%rbx),%rcx
movb $0x5,(%rcx,%rax,1)
mov 0x38(%rbx),%eax
inc %eax
mov %eax,0x38(%rbx)
mov 0x28(%rbx),%rcx
movb $0x1,(%rcx,%rax,1)
mov 0x38(%rbx),%eax
inc %eax
mov %eax,0x38(%rbx)
mov 0x28(%rbx),%rcx
movb $0x0,(%rcx,%rax,1)
incl 0x38(%rbx)
Now it looks like this:
mov 0x28(%rbx),%rax
movb $0x5,(%rax)
movb $0x1,0x1(%rax)
movb $0x0,0x2(%rax)
movl $0x3,0x38(%rbx)
