2024-04-11Fix buffer_copyEd Tanous1-4/+4
boost::asio::buffer_copy returns an integer of the number of values copied. Some static analysis tools mark that value as nodiscard, although it should never fail. Audit all uses of buffer_copy, and make sure that they're using the return value. In theory this should have no change on the behavior.

2023-08-24kvm_websocket: Fix crash on dangling referenceXinnan Xie1-7/+19
Kvm_websocket captures the this pointer in the handler lambda of the socket. When the callback is called, if the object has been destructed, there will be a crash problem. This is fixed by using weak_from_this in the callback, if the object was destructed, the callback just returns without doing anything. Tested: 1. Open two kvm sessions in WebUI, and keep refreshing in one of the pages, there is a small chance of coredump happening. Debug infomation shows: ``` bmcweb[5331]: DEBUG: doRead. conn:0x28d19a0. this: 0x284d470 bmcweb[5331]: DEBUG: doRead. conn:0x28d19a0. this: 0x284d470 bmcweb[5331]: DEBUG: doRead. conn:0x28d19a0. this: 0x284d470 bmcweb[5331]: DEBUG: doRead. conn:0x28d19a0. this: 0x284d470 bmcweb[5331]: DEBUG: doRead. conn:0x28d19a0. this: 0x284d470 bmcweb[5331]: DEBUG: onclose. conn:0x28d19a0 bmcweb[5331]: DEBUG: doRead. conn:0x2876648. this: 0x284d470 systemd[1]: bmeweb.service: Main process exited, code=dumped, status=11/SEGV systemd[1]: bmcweb.service: Failed with result 'core-dump systemd[1]: Started Start bmweb server. ``` 2.

2023-07-20Replace logging with std::formatEd Tanous1-30/+29
std::format is a much more modern logging solution, and gives us a lot more flexibility, and better compile times when doing logging. Unfortunately, given its level of compile time checks, it needs to be a method, instead of the stream style logging we had before. This requires a pretty substantial change. Fortunately, this change can be largely automated, via the script included in this commit under scripts/replace_logs.py. This is to aid people in moving their patchsets over to the new form in the short period where old patches will be based on the old logging. The intention is that this script eventually goes away. The old style logging (stream based) looked like. BMCWEB_LOG_DEBUG << "Foo " << foo; The new equivalent of the above would be: BMCWEB_LOG_DEBUG("Foo {}", foo); In the course of doing this, this also cleans up several ignored linter errors, including macro usage, and array to pointer deconstruction. Note, This patchset does remove the timestamp from the log message. In practice, this was duplicated between journald and bmcweb, and there's no need for both to exist. One design decision of note is the addition of logPtr. Because the compiler can't disambiguate between const char* and const MyThing*, it's necessary to add an explicit cast to void*. This is identical to how fmt handled it. Tested: compiled with logging meson_option enabled, and launched bmcweb Saw the usual logging, similar to what was present before: ``` [Error include/webassets.hpp:60] Unable to find or open /usr/share/www/ static file hosting disabled [Debug include/persistent_data.hpp:133] Restored Session Timeout: 1800 [Debug redfish-core/include/event_service_manager.hpp:671] Old eventService config not exist [Info src/webserver_main.cpp:59] Starting webserver on port 18080 [Error redfish-core/include/event_service_manager.hpp:1301] inotify_add_watch failed for redfish log file.

2023-01-17Add check for globalsEd Tanous1-3/+4
We don't follow this cpp core guidelines rule well. This is something that we should aspire to cleaning up in the future, but for the moment, lets turn the rule on in clang-tidy to stop the bleeding, add ignores for the things that we know need some better abstractions, and work on these over time. Most of this commit is just adding NOLINTNEXTLINE exceptions for all of our globals. There was one case in the sensor code where clang correctly noted that those globals weren't actually const, which got missed because of the use of auto. Tested: CI should be good enough for this. Passes clang-tidy. Signed-off-by: Ed Tanous <edtanous@google.com> Change-Id: Ieda08fee69a3b209d4b3e9771809a6c41524f066
2022-06-01Try to fix the lambda formatting issueEd Tanous1-43/+43
clang-tidy has a setting, LambdaBodyIndentation, which it says: "For callback-heavy code, it may improve readability to have the signature indented two levels and to use OuterScope." bmcweb is very callback heavy code. Try to enable it and see if that improves things. There are many cases where the length of a lambda call will change, and reindent the entire lambda function. This is really bad for code reviews, as it's difficult to see the lines changed. This commit should resolve it. This does have the downside of reindenting a lot of functions, which is unfortunate, but probably worth it in the long run. All changes except for the .clang-format file were made by the robot.

2021-06-16Remove ambiguous privileges constructorEd Tanous1-1/+1
There are a number of endpoints that assume that a given routes privileges are governed by a single set of privileges, instead of multiple sets ORed together. To handle this, there were two overloads of the privileges() method, one that took a vector of Privileges, and one that took an initializer_list of const char*. Unfortunately, this leads some code in AccountService to pick the wrong overload when it's called like this .privileges( {{"ConfigureUsers"}, {"ConfigureManager"}, {"ConfigureSelf"}}) This is supposed to be "User must have ConfigureUsers, or ConfigureManager, or ConfigureSelf". Currently, because it selects the wrong overload, it computes to "User must have ConfigureUsers AND ConfigureManager AND ConfigureSelf. The double braces are supposed to cause this to form a vector of Privileges, but it appears that the initializer list gets consumed, and the single invocation of initializer list is called. Interestingly, trying to put in a privileges overload of intializer_list<initializer_list<const char*>> causes the compilation to fail with an ambiguous call error, which is what I would've expected to see previously in this case, but alas, I'm only a novice when it comes to how the C++ standard works in these edge cases. This is likely due in part to the fact that they were templates of an unused template param (seemingly copied from the previous method) and SFINAE rules around templates. This commit functionally removes one of the privileges overloads, and adds a second set of braces to every privileges call that previously had a single set of braces. Previous code will not compile now, which is IMO a good thing. This likely popped up in the Node class removal, because the Node class explicitly constructs a vector of Privilege objects, ensuing it can hit the right overload Tested: Ran Redfish service validator Tested the specific use case outlined on discord with: Creating a new user with operator privilege: ``` redfishtool -S Always -u root -p 0penBmc -vvvvvvvvv -r 192.168.7.2 AccountService adduser foo mysuperPass1 Operator ``` Then attempting to list accounts: ``` curl -vvvv --insecure --user foo:mysuperPass1 https://192.168.7.2/redfish/v1/AccountService/Accounts/foo ``` Which succeeded and returned the account in question.

2020-08-17Enable clang warningsEd Tanous1-5/+5
This commit enables clang warnings, and fixes all warnings that were found. Most of these fall into a couple categories: Variable shadow issues were fixed by renaming variables unused parameter warnings were resolved by either checking error codes that had been ignored, or removing the name of the variable from the scope. Other various warnings were fixed in the best way I was able to come up with. Note, the redfish Node class is especially insidious, as it causes all imlementers to have variables for parameters, regardless of whether or not they are used. Deprecating the Node class is on my list of things to do, as it adds extra overhead, and in general isn't a useful abstraction. For now, I have simply fixed all the handlers.

2020-08-17Remove middlewaresEd Tanous1-2/+1
Middlewares, while kinda cool from an academic standpoint, make our build times even worse than they already are. Given that we only really use 1 real middleware today (token auth) and it needs to move into the parser mode anyway (for security limiting buffer sizes), we might as well use this as an opportunity to delete some code. Some other things that happen: 1. Persistent data now moves out of the crow namespace 2. App is no longer a template 3. All request_routes implementations no longer become templates. This should be a decent (unmeasured) win on compile times. This commit was part of a commit previously called "various cleanups". This separates ONLY the middleware deletion part of that. Note, this also deletes about 400 lines of hard to understand code. Change-Id: I4c19e25491a153a2aa2e4ef46fc797bcb5b3581a Signed-off-by: Ed Tanous <ed@tanous.net>
