[2.0.17] OpenTx companion crash on linux when editing input

[eephyne]

When I go to a model to edit the input (maybe mixers too but since input doesn't work…) companion crash
It seem to happen when I edit one of the input but not always, the first time if I click ok it work but if I try to add a switch for exemple it crash.

I'm on linux (arch, kernel 4.0.5 x86_64)
companion is set for 9x (I have a flysky th9x).

the stack trace is :

I currently try to build it from git to see if there is a difference

[bsongis]

Would you check with Companion 2.1.0?

[eephyne]

I just did (wanted to build master version but forgot to switch branch).

build version is 2.0.99 and it work perfectly (for now) :)

So…Can I use it without too much worries of bug or is it really unstable ? (still haven't updated radio for now)

[bsongis]

2.0.99 is out of date for sure!

[eephyne]

why its this version who was built using the next branch ?

[kilrah]

You likely did not "git pull --rebase" to get the changes that have been made since you first checked out the next branch.

[eephyne]

exactly @kilrah, I forgot that the repo was sync a long time ago.

I'm in 2.1.0 now and it work still well

I ask again, does 2.1.0 (and more generally next branch) is usually good to go or too buggy overall ?

[kilrah]

2.1 is currently in the final beta stage with release hopefully in a few days. See the open and closed issues on the 2.1 milestone.

[eephyne]

Ok

Since it final beta I assume you will not search for this bug in 2.0.17.

If this is the case, I'll mark it as solved, otherwise I'll keep it open

[projectkk2glider]

No, keep it open. I will have a look..

[projectkk2glider]

I found it 🪲 . It is also present in next.

It's a sneaky bug that was easy to fix (fix coming soon). Here is an example scenario that produces this bug:

We are editing 9X radio so input names are not used, the relevant code:

void InputsPanel::gm_openExpo(int index)
{
    // code snipped
    char inputName[4+1];
    // code snipped
    ExpoDialog *g = new ExpoDialog(this, model, &mixd, generalSettings, firmware, inputName);
    // code snipped

So, the ExpoDialog constructor gets a pointer to un-initialized inputName buffer in this case. In a release build this buffer has a random value, the trouble happens if it contains a value that resembles an UTF8 encoded string without null termination.

The ExpoDialog class uses this pointer and sets a text edit control value to this string. The control has a text length limit set to 4 characters, but if this characters happen to be UFT8 encoded then we can have a buffer overrun:

For example for inputName = "ćžšn" the strlen(inputName.toAscii().data()) is 7!

This strcpy does the buffer overrun:

void ExpoDialog::valuesChanged()
{
    // code snipped
    strcpy(inputName, ui->inputName->text().toAscii().data());
    // code snipped
