* configure: Re-configure subprojects if requiredHEADmasterlibweb-configureXavier Del Campo Romero2026-02-131-0/+17
| | | | | | | | When a configuration is changed from the top-level directory, it should be reflected on the subprojects as well. Note: still, "make clean" is required so that the objects are built with the new configuration flags.
* configure: Remove -gXavier Del Campo Romero2026-02-131-1/+1
| | | | | Traditionally, this flag is set by users via the CFLAGS environment variable, rather than including it by default.
* Honor user CFLAGS/LDFLAGSXavier Del Campo Romero2026-02-131-25/+34
| | | | | | | | | Ideally, these flags must be appended to those introduced by the project (e.g.: if user enters -Oz as CFLAGS, then -O1 and -Oz would co-exist and the compiler would choose the later), rather than replacing them. Additionally, user CFLAGS/LDFLAGS should be passed to children projects, too.
* Replace thumbnail Makefile with configure scriptXavier Del Campo Romero2026-02-135-40/+160
| | | | | | | | | The thumbnail subproject has dependencies against dynstr and ImageMagick6, which might or might not be available on the system, or might have been installed to non-standard paths. Therefore, it is more robust to rely on a configure script that checks whether the packages are available and how to deal with CFLAGS/LDFLAGS.
* configure: Also install thumbnailXavier Del Campo Romero2026-02-131-7/+14

* README.md: Add packages for Alpine LinuxXavier Del Campo Romero2026-02-131-0/+18
|
* configure: Test zlibXavier Del Campo Romero2026-02-131-1/+10
| | | | | | | | Otherwise, compilation could fail because zlib's header files and/or library cannot be found on the system. Additionally, since fdzipstream depends on zlib, zlib's ldflags must be appended to those from fdzipstream, rather than hardcoding -lz.
* configure: Test libcjsonXavier Del Campo Romero2026-02-131-1/+11
| | | | | | | | Otherwise, compilation could fail because libcjson's header files and/or library cannot be found on the system. Additionally, -lcjson should not be hardcoded to the ldflags, as this is better handled by pkg-config(1).
* README.md: Fix wrong package nameXavier Del Campo Romero2026-02-131-1/+1

* Bump libwebXavier Del Campo Romero2026-02-134-12/+41
| | | | | | | libweb has introduced several breaking changes: - Add optional expiration date to http_cookie_create - Replace Makefile with configure script
* main.c: Fix null pointer access on empty datav0.4.2Xavier Del Campo Romero2026-02-081-6/+44
| | | | | | If users send no payload data to a POST request, libweb sets a null pointer as part of the payload. Therefore, null pointers must always be checked as a sanity check.
* configure: Add libsodium flags to USERGEN_LDFLAGSXavier Del Campo Romero2026-02-031-0/+1
| | | | | Otherwise, usergen(1) would be built without linking against libsodium, and thus would fail to build.
* Bump libwebv0.4.1Xavier Del Campo Romero2025-10-261-0/+0
| | | | | | | | | | | | | The following commit fixes a memory leak caused by untrusted user input: commit 953210bd1930e1734f1acde86eadd7a1997bb7c3 Author: Xavier Del Campo Romero Date: Sun Oct 26 20:12:46 2025 +0100 form.c: Fix leak on invalid form When one or more entries have been appended to a struct form instance, but then an error occurs, those valid entries must be deallocated, too.
* README.md: Replace OpenSSL with libsodiumXavier Del Campo Romero2025-10-111-2/+2
| | | | | | | | | | This was a leftover from the following commit: commit 10e42591ac72285736d5cc4ee5e7c2f68dbf1e4b Author: Xavier Del Campo Romero Date: Wed Oct 8 13:50:52 2025 +0200 Replace OpenSSL with libsodium and argon2id
* page.c: Align results to centerv0.4.0Xavier Del Campo Romero2025-10-101-5/+5
|
* page.c: Ensure trailing '/' on dir download URLsXavier Del Campo Romero2025-10-101-1/+1
| | | | | | | Otherwise, it is not ensured web browsers would translate a relative directory such as "dir/.." to a URL with a trailing '/'. Therefore, a POST request to "/user?download=1" would fail because slcl only considers "/user/" (note the trailing '/') as valid.
* zip.c: Fix endless loop on empty archivesXavier Del Campo Romero2025-10-101-1/+1
| | | | | | | | When an empty directory is to be downloaded, z->lread would always equal zero because read_file is never called. Therefore, it is more sensible not to assume any number of bytes, and just dump as much data as possible into buf.
* zip.c: Remove unused variableXavier Del Campo Romero2025-10-101-2/+0

* Use libweb's form APIXavier Del Campo Romero2025-10-091-326/+106
| | | | | This functionality was moved from slcl to libweb since it can be shared with other web applications.
* jwt.c: Use original base64 variantXavier Del Campo Romero2025-10-091-1/+1
| | | | | | | | | | | | | | | | Otherwise, cookies set by previous, OpenSSL-based versions of slcl would be now invalidated because URL-safe base64 transforms some characters, thus breaking backwards compatiblity. For example, '/' is transformed into '_' on the example cookies below: - Original base64 encoding: a=eyJhbGciOiAiSFMyNTYiLCAidHlwIjogIkpXVCJ9.eyJuYW1lIjogImEifQ==.jgp/SsraDR/3zlAnDLyj05VHulUNbDNHaPowvUkLto4= - URL-safe base64 encoding: a=eyJhbGciOiAiSFMyNTYiLCAidHlwIjogIkpXVCJ9.eyJuYW1lIjogImEifQ==.jgp_SsraDR_3zlAnDLyj05VHulUNbDNHaPowvUkLto4=
* Allow building thumbnail from the top-level buildXavier Del Campo Romero2025-10-085-5/+34

* Replace OpenSSL with libsodium and argon2idXavier Del Campo Romero2025-10-0813-349/+845
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SHA256-based password hashing algorithm used by slcl(1) and usergen(1) is considered insecure against several kinds of attacks, including brute force attacks. [1] Therefore, a stronger password hashing algorithm based on the Argon2id key derivation function is now used by default. While OpenSSL does support Argon2id, it is only supported by very recent versions [2], which are still not packaged by most distributions as of the time of this writing. [3] As an alternative to OpenSSL, libsodium [4] had several benefits: - It provides easy-to-use functions for password hashing, base64 encoding/decoding and other cryptographic primitives used by slcl(1) and usergen(1). - It is packaged by most distributions [5], and most often only the patch version differs, which ensures good compatibility across distributions. Unfortunately, and as opposed to OpenSSL, libsodium does not come with command-line tools. Therefore, usergen(1) had to be rewritten in C. In order to maintain backwards compatiblity with existing databases, slcl(1) and usergen(1) shall support the insecure, SHA256-based password hashing algorithm. However, Argon2id shall now be the default choice for usergen(1).

* Use free function pointer for chunk/stepXavier Del Campo Romero2025-10-083-15/+10
| | | | | | libweb now supports deallocating user-defined data whenever an error occurs during a chunked transfer or an asynchronous HTTP response, thus avoiding memory leaks.
* page.c: Switch preview and downloadXavier Del Campo Romero2025-10-081-17/+35
| | | | | | | | | | | | | | | So far, clicking on a directory name previewed it, whereas clicking on a file name would download it, and file previews were on a separate column. This behaviour was found to be confusing, so it has been simplified. Now, clicking on a file or directory name would preview it. On the other hand, the "Preview" column has been replaced with a "Download" column, so that both files and directories can be downloaded. Thanks to Avron for the suggestion.

* page.c: Move remove checkbox to the rightXavier Del Campo Romero2025-10-081-1/+1
| | | | | | It feels more intuitive to keep the thumbnail and file name as first columns. It is assumed removing files and/or directories is not the main interaction from users.

* Implement directory download as ZIPXavier Del Campo Romero2025-10-0812-11/+487
| | | | | | | | | | | | | | | | | | | | | | | | Thanks to the fdzipstream library [1] and zlib [2], it is possible to generate ZIP files on-the-fly, therefore requiring no extra disk space usage and only a small amount of memory. Unfortunately, as of the time of this writing fdzipstream is not packaged by any distributions yet [3], so it had to be imported as a git submodule as a workaround. While libarchive [4] could be an interesting alternative, writing ZIP files is only supported by very recent versions (>= 3.8.0), which are still not packaged by many distributions [5], either. Moreover, libarchive is a package with several dependencies other than zlib and is significantly larger compared to fdzipstreams, so fdzipstreams was ultimately considered a better fit for this purpose.

* Setup higher backlog countXavier Del Campo Romero2025-10-062-0/+2
| | | | | libweb now allows to set up a custom value for the backlog argument in the internal call to listen(2).
* cftw.c: Call user function at the end for directoriesXavier Del Campo Romero2025-10-061-12/+24
| | | | | | | | The older, synchronous implementation for cftw recursed as long as there were children directories and, finally, it called the user function. This commit therefore fixes the newer, asynchronous implementation to honor that behaviour. Otherwise, rmdir_r would fail because rmdir(2) would be called for non-empty directories.
* jwt.c: Do not consider decoding errors as fatalsXavier Del Campo Romero2025-10-061-1/+1
| | | | | | The base64 string is considered untrusted input and, therefore, it might cause a decoding error. Therefore, this should not cause the server to close.
* Fix missing refactors related to cftwXavier Del Campo Romero2025-10-062-71/+200
| | | | | | | | | | | | | | | | | Commit 4fa1b3e8 missed to update other calls to cftw that were still relying on the older interface, causing unexpected errors. As a side effect, user quotas are now calculated asynchronously i.e., without blocking other clients. While the same improvement was planned for the /rm endpoint, it proved too challenging to implement for a first refactor: on one hand, /rm takes one or more key-value pairs involving the top-level directories and/or files to remove. On the other hand, every directory must be traversed recursively as rmdir(2) must be used on empty directories. While certainly possible, it was considered to keep a synchronous behaviour for do_rm for the sake of simplicity.

* auth.c: Fix missing username checkXavier Del Campo Romero2025-10-021-2/+5
| | | | | | | | | So far, auth_login was looking for a key that matched the expected HMAC, among all registered users, and therefore without looking up the username from the cookie key. This allowed attackers to forge a cookie with a valid key but another username, and therefore see the contents from other users.

This now allow users to search for files or directories without blocking other users, regardless how much time the search operation takes. This required cftw to deviate from the POSIX-like, blocking interface it had so far, and has been replaced now with a non-blocking interface, so that directories are inspected one entry at a time.
