SECURITY FIX
Bug#17667: An attacker has the opportunity to bypass query logging.
This adds a new, local-only printf format specifier to our *printf functions
that allows us to print known-size buffers that must not be interpreted as
NUL-terminated "strings."
It uses this format-specifier to print to the log, thus fixing this
problem.
include/my_sys.h:
Add prototype for my_memmem() .
mysys/Makefile.am:
Add reference to new file, my_memmem.c
mysys/mf_iocache2.c:
Add a "%.1234b" and "%.*b" percent-code. It takes a width, just like "%s",
but unlike the string-indicator, it requires the width and doesn't stop printing
at NUL characters.
Also, simplify the code a bit.
TODO: This code should be unified with the strings/my_vnsprintf.c code in
the future.
sql/sql_parse.cc:
The query is not a C-string, but is a sized buffer, containing any character
at all, which may include NUL characters.
strings/my_vsnprintf.c:
Add a "%.1234b" and "%.*b" percent-code. It takes a width, just like "%s",
but unlike the string-indicator, it requires the width and doesn't stop printing
at NUL characters.
tests/Makefile.am:
We may need some of our local functions.
tests/mysql_client_test.c:
Add a "%.1234b" and "%.*b" percent-code. It takes a width, just like "%s",
but unlike the string-indicator, it requires the width and doesn't stop printing
at NUL characters.
mysql-test/t/mysql_client_test.opt:
New BitKeeper file ``mysql-test/t/mysql_client_test.opt''
Add '--log' server parameter.
mysys/my_memmem.c:
New BitKeeper file ``mysys/my_memmem.c''
Implement memmem, a black-box work-alike of the GNU memmem(), which functions
like strstr() but for arbitrary blocks of memory.
