Jeges Ernő (Cydrill) előadása a HWSW free! meetup-sorozat 2021. május 19-i biztonságos szoftverfejlesztés állomásán hangzott el. A jelszavak témája örökzöld. Rengetegen gyűlölik, de kénytelenek használni nap mint nap a különböző rendszerek autentikációjához. Mi, emberek alapból képesek vagyunk elbukni erős jelszavak kialakításakor, ezért egy jó azonosító rendszer rendkívüli fontosságú. A téves értelmezéseket vesszük górcső alá, és megnézzük, mely szabályok segítik hatékonyan a védelmet – és miért.

"Translating Quake 3 into Rust"

HUP.hu - 2021, június 13 - 08:34
The Rust-loving team at Immunant has been hard at work on C2Rust, a migration framework that takes the drudgery out of migrating to Rust. Our goal is to make safety improvements to the translated Rust automatically where we can, and help the programmer do the same where we cannot. First, however, we have to build a rock-solid translator that gets people up and running in Rust. Testing on small CLI programs gets old eventually, so we decided to try translating Quake 3 into Rust. After a couple of days, we were likely the first people to ever play Quake3 in Rust!

You don't know what you are talking about, you don't know what mRNA is, and you're spreading idiotic lies. Maybe you do so unwittingly, because of bad education. Maybe you do so because you've talked to "experts" or watched youtube videos by charlatans that don't know what they are talking about.

A USA kormánya visszavonta a TikTok és a WeChat kitiltásáról szóló kormányrendeletet

US government revokes order banning TikTok and WeChat https://t.co/ZdtsH4k3Cp

— XDA (@xdadevelopers) June 9, 2021

Tavaly nyáron Trump egy kormányrendeletet írt alá, ami megtiltaná az USA-beli befektetők számára a tranzakciók többségét a TikTok-hoz és a WeChat-hez hasonló (értsd: kínai) alkalmazások mögött álló cégekkel. A kormányrendelet nagyjából azzal indokolta a lépést, hogy ezek az alkalmazások fenyegetést hordoznak a felhasználókra nézve, akinek adatai a Kínai Kommunista Párthoz kerülhetnek. Ha ezt a kormányrendeletet végrehajtanák, ezek az alkalmazások kitiltásra kerülhetnének az alkalmazás-áruházakból. Az eredeti tervek szerint november közepéig mindkét alkalmazást kitiltották volna, ha azok addig nem hoztak volna megnyugtató megoldást a velük szemben felsorolt biztonsági aggályokra.

A hírek szerint a Biden adminisztráció ezt a rendeltet visszavonja. Részletek itt.

Tom Lane pushed:

  • Doc: move some catalogs.sgml entries to the right place. pg_statistic_ext_data.stxdexpr was listed under the wrong catalog, as was pg_stats_ext.exprs. Also there was a bogus entry for pg_statistic_ext_data.stxexprs. Apparently a merge failure in commit a4d75c86b. Guillaume Lelarge and Tom Lane Discussion: https://postgr.es/m/CAECtzeUHw+w64eUFVeV_2FJviAw6oZ0wNLkmU843ZH4hAQfiWg@mail.gmail.com https://git.postgresql.org/pg/commitdiff/713a431c781fbfe1a22fae4991836077f0f4c513

  • Fix use of uninitialized variable in inline_function(). Commit e717a9a18 introduced a code path that bypassed the call of get_expr_result_type, which is not good because we need its rettupdesc result to pass to check_sql_fn_retval. We'd failed to notice right away because the code path in which check_sql_fn_retval uses that argument is fairly hard to reach in this context. It's not impossible though, and in any case inline_function would have no business assuming that check_sql_fn_retval doesn't need that value. To fix, move get_expr_result_type out of the if-block, which in turn requires moving the construction of the dummy FuncExpr out of it. Per report from Ranier Vilela. (I'm bemused by the lack of any compiler complaints...) Discussion: https://postgr.es/m/CAEudQAqBqQpQ3HruWAGU_7WaMJ7tntpk0T8k_dVtNB46DqdBgw@mail.gmail.com https://git.postgresql.org/pg/commitdiff/e30e3fdea873e4e9517c490232ea1d3bcef6c643

  • Rethink definition of pg_attribute.attcompression. Redefine '\0' (InvalidCompressionMethod) as meaning "if we need to compress, use the current setting of default_toast_compression". This allows '\0' to be a suitable default choice regardless of datatype, greatly simplifying code paths that initialize tupledescs and the like. It seems like a more user-friendly approach as well, because now the default compression choice doesn't migrate into table definitions, meaning that changing default_toast_compression is usually sufficient to flip an installation's behavior; one needn't tediously issue per-column ALTER SET COMPRESSION commands. Along the way, fix a few minor bugs and documentation issues with the per-column-compression feature. Adopt more robust APIs for SetIndexStorageProperties and GetAttributeCompression. Bump catversion because typical contents of attcompression will now be different. We could get away without doing that, but it seems better to ensure v14 installations all agree on this. (We already forced initdb for beta2, anyway.) Discussion: https://postgr.es/m/626613.1621787110@sss.pgh.pa.us https://git.postgresql.org/pg/commitdiff/e6241d8e030fbd2746b3ea3f44e728224298f35b

  • Reduce the range of OIDs reserved for genbki.pl. Commit ab596105b increased FirstBootstrapObjectId from 12000 to 13000, but we've had some push-back about that. It's worrisome to reduce the daylight between there and FirstNormalObjectId, because the number of OIDs consumed during initdb for collation objects is hard to predict. We can improve the situation by abandoning the assumption that these OIDs must be globally unique. It should be sufficient for them to be unique per-catalog. (Any code that's unhappy about that is broken anyway, since no more than per-catalog uniqueness can be guaranteed once the OID counter wraps around.) With that change, the largest OID assigned during genbki.pl (starting from a base of 10000) is a bit under

  • This allows reverting FirstBootstrapObjectId to 12000 with reasonable confidence that that will be sufficient for many years to come. We are not, at this time, abandoning the expectation that hand-assigned OIDs (below 10000) are globally unique. Someday that'll likely be necessary, but the need seems years away still. This is late for v14, but it seems worth doing it now so that downstream software doesn't have to deal with the consequences of a change in FirstBootstrapObjectId. In any case, we already bought into forcing an initdb for beta2, so another catversion bump won't hurt. Discussion: https://postgr.es/m/1665197.1622065382@sss.pgh.pa.us https://git.postgresql.org/pg/commitdiff/a4390abecf0f5152cff864e82b67e5f6c8489698

  • Doc: improve libpq service-file docs, avoid overspecifying pathnames. Clarify libpq.sgml's description of service file locations and semantics. Avoid use of backtick'ed pg_config calls to describe paths; that doesn't work on Windows, and even on Unix it's an idiom that not all readers may be instantly familiar with. Don't overspecify the locations of include files, instead writing only as much as you'd use in #include directives. The previous text in these places was incorrect for some installations, depending on where "postgresql" is in the install path. Our convention for referencing the user's home directory seems to be "~", so change the one place that spelled it "$HOME". install-windows.sgml follows the platform convention of spelling file paths with "\", so change the one place that used "/".

  • Disallow SSL renegotiation. SSL renegotiation is already disabled as of 48d23c72, however this does not prevent the server to comply with a client willing to use renegotiation. In the last couple of years, renegotiation had its set of security issues and flaws (like the recent CVE-2021-3449), and it could be possible to crash the backend with a client attempting renegotiation. This commit takes one extra step by disabling renegotiation in the backend in the same way as SSL compression (f9264d15) or tickets (97d3a0b0). OpenSSL 1.1.0h has added an option named SSL_OP_NO_RENEGOTIATION able to achieve that. In older versions there is an option called SSL3_FLAGS_NO_RENEGOTIATE_CIPHERS that was undocumented, and could be set within the SSL object created when the TLS connection opens, but I have decided not to use it, as it feels trickier to rely on, and it is not official. Note that this option is not usable in OpenSSL < 1.1.0h as the internal contents of the *SSL object are hidden to applications. SSL renegotiation concerns protocols up to TLSv1.2. Per original report from Robert Haas, with a patch based on a suggestion by Andres Freund.

  • Fix memory leak when de-toasting compressed values in VACUUM FULL/CLUSTER. VACUUM FULL and CLUSTER can be used to enforce the use of the existing compression method of a toastable column if a value currently stored is compressed with a method that does not match the column's defined method. The code in charge of decompressing and recompressing toast values at rewrite left around the detoasted values, causing an accumulation of memory allocated in TopTransactionContext. When processing large relations, this could cause the system to run out of memory. The detoasted values are not needed once their tuple is rewritten, and this commit ensures that the necessary cleanup happens. Issue introduced by bbe0a81d. The comments of the area are reordered a bit while on it.

  • Fix MSVC scripts when building with GSSAPI/Kerberos. The deliverables of upstream Kerberos on Windows are installed with paths that do not match our MSVC scripts. First, the include folder was named "inc/" in our scripts, but the upstream MSIs use "include/". Second, the build would fail with 64-bit environments as the libraries are named differently. This commit adjusts the MSVC scripts to be compatible with the latest installations of upstream, and I have checked that the compilation was able to work with the 32-bit and 64-bit installations. Special thanks to Kondo Yuta for the help in investigating the situation in hamerkop, which had an incorrect configuration for the GSS compilation.
