• Fix segfault in Authenticode hash check (#16042) (#16043)
• I noticed that r2 will crash when loading a PE file with
• Authenticode digest algorithm other than SHA-1 or MD5. I traced
• it down to the PE_(bin_pe_compute_authentihash) function returning
• NULL if it encounters an unsupported digest function. This results
• in NULL being passed to strcmp which causes the segfault.
• Solution was to add a check for PE_(bin_pe_compute_authentihash)
• returning NULL and to set bin->is_authhash_valid to NULL.
• The real solution is to add support for more algorithms but this will
• stop crashes for now.
• Greenify AppVeyor on master by using different tag name (#16041)
• Greenify AppVeyor on master by using different tag name
• Co-authored-by: Itay Cohen itaycohen23@gmail.com
• Fix read stack-based buffer overflow when using str with pk_js (#16040)
• In some cases I noticed str is not correctly terminated, so when it is
• later used in pk_js, that function reads a very long string, outside
• of the memory bounds of the original buffer.
• Add support for @* commands in new r2-shell-parser (#16038)
• Use TSSymbol instead of comparing type strings
• This patch uses ts_node_symbol instead of ts_node_type to check whether
• a node is of a given type. Since TSSymbol is just an integer, the check
• will be much faster. Also, it allows to store commands handler in an
• hashtable, instead of having if-cascade.
• Make sure r_config_hold works even when keys do not exist or are freed
• Add support for all _tmp_commands
• Make sure to always reuse the same TSLanguage
• Update both tree-sitter and radare2-shell-parser
• This way we use TSLanguage version 11, which fixes some problems with
• TSSymbols.
• Compute is_last_cmd on each single command and fix logging
• is_last_cmd should be set on a per-command basis, so if you analyze
• things like pd 3; .; .; .; the . refers to pd 3.
• This also fixes logging, so when an invalid command is parsed, it is
• still available in the history.
• Add comment about directly using r2-shell-parser in r_core_cmd_lines
• r_core_cmd_lines tries to parse the input and split it in lines, but at
• least in theory, we don't need it as the new parser can already handle
• full scripts.
• Allow other tasks to run between commands even in the new parser
• Fix #10696 - Kill r_io_map_add_next_available
• The function is just renamed to be reused and we have no tests for it, but it may fall into an infinite loop
• Fix #15842 - Add minimal slice for reproducible af test on anal-block branch
• Highlight that 'new' is a directory name in test docs (#16035)
• Use absolute URLs in pull request template (#16036)
• Fix sdb API usage to avoid extra strdup() (#16028)
• Make r_table_columns() faster, leak- and double free free (#16031)

• Fix builds by installing radare.r2 manually (#16009)
• Upload all generated ZIP files
• Use the "concatenation" concept in radare2-shell-parser
• Implement repeat_command and do not unwrap quoted args

On February 2, 2020, GitHub will capture a snapshot of every active public repository, to be preserved in the GitHub Arctic Code Vault. This data will be stored on 3,500-foot film reels, provided and encoded by Piql, a Norwegian company that specializes in very-long-term data storage. The film technology relies on silver halides on polyester. This medium has a lifespan of 500 years as measured by the ISO; simulated aging tests indicate Piql’s film will last twice as long.

To Review

• Release 4.2.0 - Arctic World Archive
• Fix resizing issue (#15863)
• Fix pkgname version check for real now (#15862)
• Enable V testsuite on GitHub CI (#15796)
• Enable V testsuite on GitHub CI
• Check version for pkgname correctly (#15860)
• dot can be null
• Using R2_VERSION_MAJOR/MINOR is wrong because they will be continuously updated and we want to check for exactly 4.2.0
• The version check logic itself was wrong
• Fix afb test (#15861)
• Fix #15833 - Only print pkgname if the plugin is for r2 >= 4.2
• Update/improve jmptbl size tests
• Use specific commit of V to avoid build issues
• A bit more picky fix
• Add test for afs without type
• Fix #15767 - Temporarily disable colors in drrj
• Fix warnings
• Update radare2-shell-parser
• Use void because we don't do anything with the return value
• Coverity fixes
• Remove the wrong test
• More tests fixes
• Resizing works not perfectly yet but close
• Fix #15604: Convert all tests from <<KEYWORD to <<EOF
• Fix wrong tests (#15834)
• Add test for env variables boolification
• Introduce SETBPREF to handle "boolish" vars like asm.cmt.off
• Do not try to convert to true/false, as it breaks integer vars
• See discussion at #15681 .
• Unfortunately the change cannot be done for non-int vars only, because
• right now vars are not statically typed, so a var that is initially
• CN_INT can then become CN_STR if you set a string.
• Changing vars to assign them a static type when they are created would
• require a much bigger change and discussion.
• A bit of refactoring in r_config.h
• Move all version defines into r_version.h and handle it from meson too
• • R2_VERSION_MAJOR
• • R2_VERSION_MINOR
• • R2_VERSION_PATCH
• • R2_VERSION_NUMBER
• Mach-O io: mem leak fix proposal. (#15829)
• C89 Fixup for r_sign_fcn_types function (#15824)
• Fix error: for loop initial declarations are only allowed in C99 mode
• Implement new zignature types format
• Adapt zignature types deserialization to new format
• Integrate fcn types when zignatures match
• Use node->i_value in the log.level/log.traplevel callbacks
• Basic Blocks are now global instead of owned by a single function.
• Fix dbg_bps tests that always succeeded (#15763)
• Approved-by: Riccardo Schirone sirmy15@gmail.com
• This feature only works with server implementations that have ReverseStep
• and ReverseContinue enabled, such as rr. The official gdbserver doesn't support it.
• Remove opt->sz checks and operations in r_bin_open_buf
• opt->sz is not used anyway in r_bin_open_buf, so there's no need to
• check its value or compute it.
• Fix last coverities related to cbin
• Add test for a8 command
• Some more coverity fixes (#15802)
• Implement pcV command to print byte array in Vlang
• Fix a small bug by removing some useless codes (#15795)

• C prototypes fixed
• Fix broken AppVeyor due to rejected apostrophes (#15785)
• Some coverity fixes
• Third fix attepmt for musl builds
• Second fix attempt for Alpine/musl builds
• Aim to fix the alpine build
• The plugin wouldn't properly trace breakpoint hits on different threads
• since they weren't switched to and the events weren't always handled.
• Also, since the breakpoints are removed after they are found in one of the
• threads, it's best to stop all threads for now even if dbg.threads is false.
• New threads were only added after being attached to manually or if
• dbg->trace_clone was true. dbg->trace_clone stops debug and switches the
• new thread now.
• Fix a format string vuln in the disassembly with comments (#15783)
• Add s390x reg profile
• Add missing pc register
• Use gregset instead of regset
• ww: Support esc seqs (#15780)
• Breakpoints were left in disassembly after a signal/break and there
• are probably other cases that may lead to it.
• Offset for each panel was not correct (#15778)
• Add null to pj and use for relocs (#15776)
• Add pj_null() and pj_knull()
• Print reloc name as null in json if not available
• Omit reloc name in json
• Improve shell injection check
• Fix Coverity fixes (#15779)
• Some coverity fixes
• Fix #15331 - rabin2 -rk code injection issue (#15678)
• Rewrite r_str_unescape() using switch
• Do not compile radare2-shell-parser by default (#15769)
• Last release (4.1.0) did compile it by default, but the build requires
• internet access to download the repositories. For now, since the feature
• is anyway very experimental, we disable it at compile time so that
• distributions can just compile their packages without internet access.
• In the future we may want to use submodules or augment the release
• tarball to include the tree-sitter and radare2-shell-parser archives.
• Pass 64-bit sdb_fmt parameters as 64-bit (#15758)
• Fix double free in r_bp_del_index and other breakpoint index bugs
• Lack of cleanup in r_bp_del_all causing use after free in other dbi
• commands
• Copy paste error turning dbix into dbx
• Add dbi- command
• Allow dbi commands to operate with index 0
• izzzj: Use pj api (#15760)
• Some xmm registers were printed as fpu and bnd registers were shown in
• all drt categories.
• dr will still only show 64bit/32bit registers to avoid printing all
• of the flags and d/w/b register variants.
• This fixes situations that if a read contained even a byte inside invalid memory, the entire read would fail
• Added RCoreBind.syncDebugMaps() and RCoreBind.getDebugMaps() api
• Reenable db tests and add new tests to check validity
• Add perm check to isMapped and remove map sync to improve performance
• Fix two tests
• Add RCoreBind.isMapped() api
• This reverts commit e503bdd.
• This way it is possible to set breakpoints before starting debug through
• 'db' and the user will be notified when a breakpoint points to an
• invalid map.
• Instead of unsetting breakpoints they were set again without removing
• the previous drx values, which also caused the "Invalid DRX length (0)
• must be 1, 2, 4, 8 bytes" error because of the wrong len values.
• Also, when resetting twice, del failed since there weren't any hw
• registers to delete, which caused the "hw breakpoints not yet
• Shows the module, offset and function name instead of showing the executable's
• path for all threads
• Upgrade node-r2r 0.2.8 (#15751)
• Fix windows dp showing the parent's path for all processes (#15741)
• Fix #15734 - Automatically download PDB file if pdb.autoload=1 (#15738)
• Automatically download PDB file if pdb.autoload=1
• Don't re-download pdb if it already exists on the symstore
• Only download if file doesn't exist

• Fix infinite loop in panels - vttq (#15729)
• Check for error when analyzing instructions in vmenus
• Fix #15719: Reduce false negatives in 'U' strfilter
• Added path escape and unescape
• Unescape paths only if r_str_argv was successful
• Use r_str_replace instead of r_str_arg_(un/)escape to avoid breaking escaped filenames
• Fix debug and 'o' not being able to open paths with spaces #debug
• After starting debug the register deltas weren't mapped to the same
• registers in remote and native debug. This made wrong registers appear
• as vars and in remote gdb none showed up since the remote's list is much
• shorter than r2 reg lists.
• Kill some more tests using <<RUN
• Improve r2r.v quite a lot up to 0.2
• Delete stale temporal files in the unit test
• Use executable path instead of dbpath and more cleanup
• Move manpage and move old bins into the attic
• This api honors ansi escape characters
• Delete the use and definition of "eprint" (#15716)

• Fix some warnings
• Remove unnecessary duplication
• Co-authored-by: Anton Kochkov xvilka@gmail.com
• Few warning build fixes proposal.
• attach_new_process was called instead of regular attach because the
• saved pid and tid in core->dbg weren't reset before calling r_debug_select
• in a new session. Made sure this won't be a problem when using dp= after
• dp- either.
• Calculate the diff ourselves since bp->delta is calculated with the
• dbg->bp->baddr at the time of breakpoint creation, which may not
• reflect the correct baddr and break the rebase.
• Previously, disabled breakpoints were restored and then hit during
• execution. The debug logic ignored them and continued but that's
• an unnecessary slow down. To achieve this type of behavior the user
• should use tracepoints.
• Minor syntax issues in panels
• Use v fmt to indent the new testsuite
• Change Semantics of r_rbtree_upper_bound() and simplify Iter Fcns (#15698)
• Remove RAnalBlock members only used in Java (#15679)
