If the source string has a run of more than 256 runes without
a "." dot, we'd overflow the runebuffer in idn2utf().
The utf2idn() routine had a check in the while loop, but that
is actually wrong too, as it would insert a dot and restart
the loop in the middle of a domain component. Just error
out if a domain component is too long.
- allow for external command to be run to install a challenge using -e flag
- remove the challengedom argument, it is given by the subject in the csr
- fix some filedescriptor leaks in error paths
In a few places, we where using a fixed buffer of sizeof(Dir)+100
size for stat. This is not correct and fails if the name returned
in stat is long.
This results in being unable to seek to the end of file with a
long filename.
The kernel should do the same thing as dirfstat() from libc;
handling the conversion and buffer allocation and returning a
freeable Dir* pointer.
For this, a new dirchanstat() function was added.
The fstat syscall was not rewriting the name to the last path
element; fix it.
In addition, gracefully handle the mountfix case, reallocating
the buffer to accomidate the required stat length plus
size of the new name so dirsetname() does not fail.
this patch fixes bugs in tls extension handling:
1. if conn->serverName is an empty string, tlsClientExtensions
will generate a SNI with an empty hostname, which is forbidden
according to RFC 6066:
opaque HostName<1..2^16-1>;
check if conn->serverName has at least one char.
2. checkClientExtensions fail with clients that doesn't have
extensions, because it doesn't check if ext is nil. fix that
up.
3. rewrite checkClientExtensions. some parts of the code does
not check the length properly, and it could be simplified
heavily.
The standard states in section 19.5.93:
.... Notice that if this operation is performed
on an obeject reference such as one produced by
the Alias, Index, or RefOf statements, the obect
type of the base object is returned.
Do the debuglevel check before calling the print
function for _threaddebug, by making it a macro.
Do not waste cycles passing arguments.
Generalize the _threaddebug function into _threadprint()
and add a varargcheck pragma. This function can
also be used from _threadassert().
Fix missing arguments in one case, fix trailing
newlines in _threaddebug().
Make _threadgetproc()/_threadsetproc() a macro,
just dereferencing Proc**_threadprocp.
Simplify the mainjump, just call _threadsetproc()
directly without that mainp dance. Remove the
_schedinit() argument, it uses _threadgetproc() now.
Get rid of Mainarg struct, just have a global variable
for argc.
