Turns out that we were only recording the "b_digest" but to have bidirectionnal authenticated SENDMEs, we need to use the "f_digest" in the forward cell situation. Because of the cpath refactoring, this commit plays with the crypt_path_ and relay_crypto_t API a little bit in order to respect the abstractions. Previously, we would record the cell digest as the SENDME digest in the decrypt cell function but to avoid code duplication (both directions needs to record), we now do that right after iff the cell is recognized (at the edge). It is now done in circuit_receive_relay_cell() instead. We now also record the cell digest as the SENDME digest in both relay cell encryption functions since they are split depending on the direction. relay_encrypt_cell_outbound() and relay_encrypt_cell_inbound() need to consider recording the cell digest depending on their direction (f vs b digest).

The scripts directory holds tools for use in building, generating, testing, and maintaining the Tor source code. It is mainly for use by developers. Code maintenance scripts ------------------------ maint/checkLogs.pl -- Verify that Tor log statements are unique. maint/check_config_macros.pl -- Look for autoconf tests whose results are never used. maint/checkOptionDocs.pl -- Make sure that Tor options are documented in the manpage, and that the manpage only documents real Tor options. maint/checkSpaces.pl -- Style checker for the Tor source code. Mainly checks whitespace. maint/findMergedChanges.pl -- Find a set of changes/* files that have been merged into an upstream version. maint/format_changelog.py -- Flow the changelog into the proper format. maint/redox.py -- Find places that should have DOCDOC comments to indicate a need for doxygen comments, and put those comments there. maint/updateVersions.pl -- Update the version number in the .nsi and windows orconfig.h files. Testing scripts --------------- test/chutney-git-bisect.sh -- a git bisect run script that bisects using chutney. The script builds tor and tor-gencert, then runs chutney. The script takes optional arguments for out-of-tree builds, and specific chutney network flavours. You should copy this script before using it with git bisect, so that it doesn't change (or disappear) during bisection. test/cov-blame -- Mash up the results of gcov with git blame. Mainly useful to find out who has been writing untested code. test/cov-diff -- Compare two directories of gcov files to identify changed lines without coverage. test/coverage -- Generates a directory full of gcov files. You need to use this script instead of calling gcov directly because of our confusingly named object files. test/scan-build.sh -- Example script for invoking clang's scan-build static analysis tools. Code generation scripts ----------------------- codegen/gen_linux_syscalls.pl -- Generate a table mapping linux syscall numbers to their names. codegen/gen_server_ciphers.py -- Generate a sorted list of TLS ciphersuites for servers to choose from. codegen/get_mozilla_ciphers.py -- Generate a list of TLS ciphersuites for clients to use in order to look like Firefox. Code transformation scripts --------------------------- coccinelle/calloc.cocci -- Transform code to replace variants of malloc(a*b) with calloc(a,b)
